Roll thermal insulation for pipes. Thermal insulation for water supply pipes: an overview of insulation against freezing pipes in the ground

Pipe insulation is a material that guarantees efficient work systems, conservation comfortable temperature in the house and uninterrupted circulation of the contents of the highway. In the conditions of our latitudes, all communications have to be insulated. The choice of thermal insulation is a responsible task, which is not easy to cope with, given the wide range. A small tour of options- in this review from the editors of HouseChief.

Thermal insulation: an urgent need or reinsurance

The ground freezes in almost all our latitudes. If a pipeline with liquid contents is in the frozen ground, it will most likely break. In addition, direct contact with cold soil or air leads to significant heat loss. Part of the thermal energy will be wasted on heating the environment and will not reach its destination.

In houses, the boiler room is often located outside the main room, and the coolant has to travel some distance before getting into the radiators. The route of the highway can pass through the attic, basement or unheated corridor.

The sewerage system is also very dependent on temperature. Even if the line is laid according to all the rules, with the necessary slope, plaque forms inside the pipes, which, when frozen, can clog the system and lead to pipe rupture. Not only centralized systems are subject to such problems, but also autonomous structures with a septic tank.

There is always water in the pipes. It begins to circulate when the tap is opened, and the rest of the time it can turn into ice in the freezing soil.

So there is no question of reinsurance. Thermal insulation is a really necessary procedure that should not be neglected if you do not want to constantly repair engineering networks.

Requirements for heat insulators for pipelines

In order for the heater to effectively perform its task, it must meet several important requirements:

• the level of thermal conductivity should be as low as possible to effectively maintain the temperature of the contents of the line in the cold and warm seasons;
• thermal insulation must be safe for humans;
• the material must not be flammable and must not support combustion;
• the insulation should not accumulate moisture, as this process reduces its ability to retain heat;
• installation of the material should be simple, with a minimum number of joints and the possibility of isolating nodes of complex configuration;
• the maintainability of the insulation and the possibility of its repeated use are important;
• the material must be resistant to external influences, mechanical, atmospheric and chemical, as well as to a sharp temperature drop.

What heaters meet these requirements? There are several options that are great for pipe insulation: these are mineral wool materials, foam thermal insulators, and some bulk and liquid substances that can perform such tasks.

Types of insulation for pipes and their features

Consider the main options for heat insulators, which are most effective for insulating sewerage, heating and plumbing systems.

Mineral wool materials

Fiberglass or stone wool retains heat very well. If we compare these two types of insulation, then stone wool wins in terms of insulating properties. It withstands temperatures up to 700ºС and keeps its shape perfectly even under mechanical stress. This insulation is resistant to aggressive chemicals and is relatively inexpensive.

But he also has his own unpleasant features. The main one is the ability to absorb moisture. With this process, stone wool gradually loses its heat-insulating properties. Therefore, if you opt for this material, you should consider another outer layer of waterproofing to protect against water.

Expanded polystyrene insulation

Foam insulation contains more than 50% air in its mass, which makes it one of the best. Its only drawback is its fragility, which does not allow it to be bent in the shape of a pipe. But manufacturers have solved this problem by releasing a foam shell, which has the shape of a half-cylinder and can be worn on a pipe like a shirt.

Such a shell withstands temperature fluctuations from -110ºС to + 80ºС degrees. If your heating pipes heat up to a higher temperature, then a cork membrane should be laid between them and the foam.

Such a heater does not support combustion and can be used more than once.

A more perfect version of the shell is penoplex, which, with a smaller thickness, has better heat-insulating properties. Penoplex is more elastic, so it can bend a little if necessary.

Liquid penoizol

This material is applied by spraying and is used more often for insulating pipes in industrial premises. After such treatment, the pipe is completely hidden under the insulator layer, without the formation of cold bridges. In this way it is convenient to insulate pipes with a complex configuration. Spraying services are not cheap. In a private household, an analogue of such insulation can be the usual polyurethane foam.

Foamed polyethylene

Polyethylene is a fairly durable material that can withstand mechanical loads well. This type of insulation is not afraid of moisture and protects metal pipes from corrosion damage. Temperature range of operation – from -60ºС to +90ºС. Foamed polyethylene resists fire for a long time, but if it burns, it does not emit toxins.

The price of foamed polyethylene is an order of magnitude lower than, for example, polyurethane. Thermal insulation for pipes made of this material is produced in the form of hollow cylinders up to 200 cm long and up to 20 mm wall thickness.

To put such a cylinder on a pipe, it is cut lengthwise, and then the cut is sealed with adhesive tape. Rolled material is simply wrapped around pipes.

Foil penofol

Foil insulation is a modern and popular type of thermal insulation, easy to install and efficient in operation. Foil penofol can also be used to insulate pipes. It is produced in rolls and hollow cylinders.

Energoflex

This type of insulation is flexible. In fact, Energoflex is a kind of foamed polyethylene high pressure. This material can be used outdoors. It is not afraid of water and can withstand temperatures from -60ºС to +90ºС.

Available in rolls and hollow cylinders.

The disadvantage of Energoflex is its susceptibility to direct ultraviolet radiation.

Heat insulating dyes

It's comparatively the new kind thermal insulation, which is applied with a conventional brush or roller. The thickness of the resulting layer is minimal, and the thermal insulation effect is quite high. The price of such paints "bites", and the secret of their manufacture is vigilantly kept by manufacturers. It is only known that the heat-insulating effect is present due to the presence of microspheres with air in the composition of the paint. Such a coating can replace a five-centimeter layer of mineral wool.

Loose insulation

In addition to the materials listed, pipes in the ground are traditionally insulated with expanded clay. The layer of this material is able to retain heat qualitatively and for a long time. So that the insulation does not mix with the soil, it is placed together with pipes in a box made of boards or in concrete shells.

Thermal insulation for pipes: how to choose

The choice of insulation depends on three main factors: the location of the pipeline, installation features and cost. In principle, any of the heaters listed above is easy to install with your own hands.

Foil insulation is used to keep pipes from overheating from the outside. In terms of material cost, mineral wool will be the most expensive, and polyethylene foam will be the cheapest.

In the case when it is impossible to wrap the pipes with a heat insulator due to their complex structure or location, it is logical to use thermal paint.

For heating system

For the heating system, heat-insulating materials should be used that can be operated in contact with high-temperature objects. These include mineral wool, foam plastic and polyurethane foam.

Two conditions are important for the insulation of a water supply system: maximum heat retention and protection against corrosion. The most suitable for this are polyurethane foam, which is applied in a liquid state, and heat-insulating paint. Both of these options eliminate the formation of condensate and protect pipes from rust.

For sewerage

Sewer pipes with insufficient slope or passing less than half a meter from the ground surface must be insulated. This will require materials that do not absorb moisture and are resistant to mechanical stress.

How to independently install insulation on pipes

Installation of thermal insulation on pipes is quite simple task, which even a beginner can solve. Here is a short video on this topic that will help you quickly understand the process:

Some nuances of installation in special conditions

To obtain effective insulation of pipe lines, you should follow a few simple recommendations:

• when insulating in unheated rooms, it is important to exclude cold bridges;
• in wet rooms, vapor barrier should be used over thermal insulation;
• the insulation with a self-adhesive layer will greatly facilitate the installation work;
• to eliminate minor flaws in installation, use additional winding and reinforcing tape;
• carefully select hard insulation - they must exactly match the diameter of the pipes.

Effective operation of modern pipelines of cold and hot water supply is unthinkable without high-quality thermal insulation. Thermal insulation performs several important functions at once: the most important of them is the reduction of heat energy losses. Additionally, it protects engineering networks from mechanical damage, pipe corrosion and condensation. As a result, the service life is significantly extended, and repair costs are reduced.

Pipe insulation is widely used in various fields and industries. Today, heat-insulating materials are used in the installation of pipelines for various purposes. These are mainly pipelines for hot and cold water supply, heating, ventilation, and sewerage systems. High-quality thermal insulation helps to solve many problems of various engineering systems, and most importantly - extends the service life of networks and saves both resources and money.

Thermal insulation of pipes of domestic and industrial pipelines has been used everywhere and for a very long time. Depending on the type of pipeline (underground / aboveground), the corresponding type is also used thermal insulation materials. For greater efficiency of the system, insulation of shut-off and control valves, fittings, etc. is also used.

Types of thermal insulation materials:

Today there is a wide range of materials for thermal insulation of pipes. Each material has its own characteristics and purpose. They differ in resistance to steam, corrosion, and finally, service life.

• Made from polyethylene foam.
• Made of foamed synthetic rubber.
• From polyurethane foam.
• From expanded polystyrene (styrofoam).
• From basalt fiber.

For example, thermal insulation for polyethylene foam pipes is a rolled heat and sound insulating material. This type thermal insulation is characterized by high thermal insulation properties, available in the form of sheets, pipes and bundles. This exceptionally strong and elastic material is resistant to aggressive environments, is durable and moisture resistant. It effectively reduces both heat loss and noise. Protects the surface from corrosion and accumulation of condensate.

External thermal insulation for cold water pipes also plays an important role. It prevents the appearance of condensate and corrosion, reduces noise from passing streams. High-quality insulation will help to avoid such an unpleasant effect as freezing of pipes even in severe frosts in winter. In a word, insulation ensures the normal functioning of networks and extends the service life.

Why pipe insulation is necessary

Insulation of the pipeline today is necessary for many reasons. For example, in cold winter time high-quality pipe insulation will provide protection against freezing, reduce heat loss, and most importantly, extend the life of the system.

Thermal insulation and its advantages:

• Provides long service life.
• Reduces heat loss (especially in winter).
• Protects the pipeline from damage, corrosion, condensate.
• Helps prevent freezing in winter.
• Reduces noise.

All of the above applies not only to industrial pipelines, but also to domestic heating systems. This avoids many problems in the winter, when even steel and metal-plastic pipes freeze.

Thermal insulation for professionals and those who like to save

In our online store "Terem" you can buy high-quality thermal insulation for pipes and underfloor heating various kinds. In the catalog you will find 100% original products of world famous brands - K-FLEX and Energoflex.

The products of these companies are highly valued both among professionals and among ordinary people who want to improve the security and efficiency of water supply and heating systems for private homes.

Thermal insulation of heating pipes performs a number of functions. It reduces heat loss along the path of the coolant and increases the efficiency of the heating system. Insulation protects metal structures from condensation and slows down the corrosion process. In case of fluid stagnation in the pipes, it does not freeze and does not damage the collectors. What materials are used for thermal protection and how they are mounted, this article will tell.

Materials for thermal insulation of heating pipes

The choice of insulation is a task in which the following factors are taken into account:

• maximum coolant temperature;
• conditions for servicing the heating system;
• pipe diameter.

Depending on the capacity of the pipeline, the following types of thermal insulation are used:

• finished cylinders;
• semi-cylinders, when the cylinder is made up of two halves;
• roll materials, which can be given the desired shape.

For pipelines of small diameter, rigid elements in the form of cylinders and half-cylinders are suitable. They are equipped with grooves and holes, the presence of which simplifies and speeds up the process of mounting the containment. Such thermal insulation for heating pipes protects the collectors from mechanical damage, helps to endure high temperatures and absorbs moisture minimally.

Mineral wool

Mineral wool has not lost popularity for decades. The reason lies in the proven result of their application and affordable cost. The materials are used for insulation of heating systems of industrial and civil structures. Traditionally, it is used where structures are constantly exposed to temperature changes, for example, to insulate furnace chimneys.

In construction, insulation is valued for the following properties:

• resistance to acids, alkalis and solutions;
• weak water absorption (depends on the processing of the material with special compounds);
• the material perceives up to 600 ° C, without losing mechanical and thermal insulation qualities;
• safety for the environment.

Of all mineral heaters, the following stand out:

• basalt wool (made from basalt rocks);
• glass wool (made from broken glass or staple fibers derived quartz sand).

The temperature resistance threshold of basalt wool is higher. Therefore, its scope is wider than that of fiberglass, which is used in the construction of residential facilities. Fiberglass enters the distribution network in rolls with a web thickness of 15-20 cm. The material consists of fibers 3-4 microns thick. Insulation is used to insulate structures whose temperature does not exceed 1800 ° C. It is not destroyed by vibration, is resistant to chemical processes and has a long service life. Such material protects heating mains located on the surface of the earth.

Note! Fiberglass is a hazard to those who work with it, as the dust irritates the mucous membranes of the eyes and skin. Therefore, when installing such thermal insulation for pipes for heating, be sure to use special means protection.

polyurethane foam

This heat insulator is superior to heaters made from mineral wool. It has a dense, rigid shape, which is why it was called the "shell". It is produced by the “pipe in pipe” method, when the space located between two cylinders is filled with a prepolymer substance. It forms a protective "shell".

Polyurethane foam, familiar to many as polyurethane foam (used to blow out cracks in window frames), has the following advantages:

• does not emit toxic substances and does not smell;
• does not disintegrate and does not rot under the influence of external factors;
• does not pose a risk to human health;
• does not decompose in an alkaline and acid environment;
• does not respond to changes in humidity and temperature jumps;
• not destroyed by sun rays, since the material is covered with a protective paint during installation.

The only drawback of the polymer is the cost.

Foamed polyethylene

Another synthetic material is polyethylene foam. It also does not pose a danger to the human body and the environment, without loss endures sharp fluctuations in external temperature and air humidity.

For ease of installation, the insulation is made in the form of tubes with a notch. Cold and hot pipelines are insulated with polyethylene. Since such thermal protection does not tolerate high temperatures, it cannot be used to insulate heating pipes on the street. The use of such an insulating material is limited to residential buildings only.

This material needs no introduction. It has long been used for various purposes and is characterized by low thermal conductivity and water-repellent properties. The reasonable price of the heater explains its popularity. They are insulated with metal and plastic structures and used as sound insulation.

The liquid type of penoizol foam is used for thermal insulation of heating mains. When applying the material to the pipes, voids and gaps do not appear, and after drying, a solid crust is formed.

Foam glass

Insulation refers to the latest innovations building materials. Cellular glass reliably protects pipes and other structures. The material has the following advantages:

• environmentally friendly;
• resistant to acids and alkalis;
• not combustible;
• does not shrink;
• not of interest to rodents;
• not difficult to install;
• has a long service life.

Such characteristics did not go unnoticed by experienced builders and novice installers. Therefore, they turn to him more and more often.

Do-it-yourself pipe insulation

Thermal insulation for outdoor heating pipes is carried out along the entire length of the heating main. For this, ready-made protective elements with layers of waterproofing and insulation are used. Their considerable cost pays off by significant time savings during the installation of insulation. This is especially noticeable when work is carried out on long highways. In this case, it is enough to make reliable insulation of the joints.

If you use other materials and do the work yourself, you will need:

• foil tape;
• selected insulation;
• adhesive tape to isolate the junctions of elements.

Having prepared everything you need, get to work.

1. Stick the foil tape on the pipes, moving forward in a spiral.
2. Fasten or install insulating material. Make sure that the connecting seams are tightly adjacent to each other.
3. To prevent penetration into the seams ground water, fix the joints with a special plumbing tape.

Note! Where seasonal temperatures are very low, it is advisable to use the insulation method using a special cable for heating pipes.

What thermal insulation for heating pipes is most effective

The basis of any heating system is heating pipes. In order to prevent pipes from freezing during the autumn-spring period of the year, condensation or corrosion does not appear on them, and when the system is idle, the transferred water does not turn into ice, thermal insulation is used for heating pipes. This article will talk about the varieties of insulating materials and how to use them.

Material selection

In areas with a predominantly cold climate, thermal insulation for pipes - necessary condition functioning of heating systems of any type - central or domestic.

When choosing a material for insulating heating pipes, the following initial data should be taken into account:

• pipe section;
• the conditions under which the heating system operates;
• temperature of the transported coolant.

It depends on the section of the pipe what form the heat-insulating material should be purchased - in a roll or in the form of half-cylinders, cylinders of available sizes.

For example, if you want to insulate pipes not large diameter, it is better to use heat-insulating materials for heating pipelines of a cylindrical or semi-cylindrical shape. Such products, in addition, due to their rigidity and elasticity, serve to protect the system from mechanical damage, and also have water-repellent properties. In the case of large diameters, you will have to use roll insulation.

For right choice thermal insulation need to consider the main types of products used.

Types of thermal insulation for pipes

Mineral wool

Mineral wool for pipelines is one of the most popular insulating materials. This insulation is recommended for insulating central heating and supply systems. hot water laid in residential buildings or buildings industrial enterprises. Another way to use the material is to protect pipes with constant heating, for example, stove chimneys.

There are two types of mineral wool:

1. Stone wool - made from basalt rocks.
2. Glass wool (fiberglass) - produced from broken glass or staple fiber, the basis of which is quartz sand.

The main advantages of stone wool:

• heat resistance (up to 650°C) while maintaining mechanical properties;
• resistance to solvents (alkalis, acids, oil solutions, etc.);
• with special impregnation, moisture resistance can be given to cotton wool;
• environmentally friendly, non-toxic material.

Glass wool is less heat-resistant, respectively, the scope of its application is narrower. It is produced in rolls 1.55-2 m long.

• operating temperature of protected pipes - up to 180°С;
• vibration resistance;
• chemically neutral, does not interact with chemical and biological substances;
• with proper installation and observance of operating conditions, it retains its properties for a long time.

polyurethane foam

This thermal insulator has a rigid shape, providing edges and walls. Finished products are obtained by casting "pipe in pipe". Due to the above properties, the material is often called a shell.

Polyurethane foam has maximum strength and effectively reduces heat transfer.

Technological characteristics of polyurethane foam:

• non-toxic, no smell;
• resistance to oxidation (does not rot);
• unsurpassed strength - serves not only as a thermal insulating element, but also as a mechanical protection for pipes;
• does not conduct electricity;
• chemically resistant - does not interact with acids, alkalis, etc.;
• suitable for any climate and all weather conditions.

The main drawback of the product is the high price: polyurethane foam insulation is more expensive than the rest.

Polyethylene foam

This type of thermal insulation is produced in the form of hollow cylinders for different outer diameters of pipes. The usual length of the cylinder is 2 m, variations are possible.

Foamed polyethylene can be used to insulate heating pipes, hot and cold water pipes.

Advantages of polyethylene foam:

• environmentally friendly material, safe for humans;
• moisture resistance;
• good thermal insulation, resistance to temperature changes;
• elasticity combined with flexibility allows the material to be used both as insulation and as mechanical protection pipeline;
• ease of use - can be put on the pipe as a whole or by cutting the cylinder;
• retains properties in the vicinity of lime, concrete and other materials.

Other foam insulation

In addition to foamed polyethylene, for the purpose of thermal insulation, they use:

• expanded polystyrene - supplied in the form of halves connected by a ledge into a groove;
• polystyrene foam - has good hydro, thermal and sound insulation, is resistant to ignition, with proper operation, the service life exceeds 50 years; besides, cheap;
• penoizol - sold in the form of a liquid, when applied to the surface it foams without leaving gaps;
• foam glass - glass of a cellular structure, safe, does not shrink, non-combustible, durable, chemically neutral, resistant to rodents.

Heat insulating paint

Thermal insulation paint for heating pipes – new material developed in Russia.

The composition of the paint includes:

• foam glass;
• ceramic microspheres;
• perlite;
• other heat-insulating substances.

Applying a layer of paint 2 mm thick is equivalent to wrapping the pipe with several layers of mineral wool or expanded polystyrene.

• non-toxic, safe for health;
• has no smell;
• protects pipes from corrosion;
• withstands heating to high temperatures;
• can be used in both domestic and industrial heating systems.

Such paint is produced in the form of an aerosol, which allows you to apply the material to hard-to-reach sections of the pipeline.

Installation of thermal insulation on the pipeline

Before you begin directly work on the installation of insulation, you must go through several preparatory stages.

First, the insulation material must be selected. You can be guided in this paragraph by the expected operating conditions (operating temperature, the possibility of mechanical deformation, the presence of rodents), and the diameter of the pipes (it is obvious that hollow cylinders, for example, made of polyethylene foam, are ideal for a small diameter, and large diameter pipes are easier to wrap with glass wool ).

Another important factor is the price of the product. Of course, if the cost of carrying out the work is not limited, you can choose modern material with higher performance; however, traditional types of thermal insulation have not lost their relevance.

In addition, if the work will be carried out in hard-to-reach places, it is more logical to use easily applied materials - thermal insulation paint or penoizol.

Secondly, it is necessary to free access to the insulated pipes as much as possible in advance, trying to remove all obstacles. As a result, this will significantly speed up the work and prevent possible injuries or damage to consumables, which means unnecessary expenses.

After the preparatory steps, the material is actually fixed on the pipe.

The order of work is as follows:

1. Before applying the insulation, the pipes are covered in a spiral with tape-foil.
2. The insulation is wrapped around the pipe or otherwise applied or fixed to the surface. Regardless of the method of application, work should be done in good faith, avoiding leaving open areas that will later become “cold bridges”.
3. After fixing insulating material on the surface of the pipe, it is additionally fixed with adhesive tape (for example, plumbing), wrapping it in several layers. Winding should also be done as carefully as possible and with a certain effort.

If the work is done carefully and no gross errors were made, the thermal insulation, regardless of the material chosen, will serve for a long time and properly.

How to insulate heating pipes with your own hands - the choice and installation of pipe insulation

The heat loss in the pipeline is the main problem both autonomous and central pipelines of the heating system. And if the reduction of heat loss within the region is entrusted to utilities, then the owner of a private house needs to take care of the insulation of the heating pipes on his own, and due to the insignificant amount of work, do it yourself.

Is it necessary to insulate heating pipes and what does it give?

Thermal insulation for heating pipes allows you to:

• reduce heat loss in places where pipes run along the ground, are installed by air (ground) or located in an unheated room;

• prevent freezing of the liquid, which is the coolant (freezing is fraught with a pipe break);

• reducing the likelihood of corrosion on the surface of the pipe (for metal pipelines);

• saving money on home heating.

Thus, the more reliably the heating system is insulated, the more heat the user will get (the higher the efficiency), and the less he will have to pay for gas for heating (or for electricity, if an electric boiler).

Due to the fact that a coolant is moving through the heating system, the task of pipe insulation is reduced to minimizing heat loss and preventing system rupture due to freezing.

A popular solution in this case is the use of thermal insulation materials. This is the most budgetary and simple way of warming from the point of view of self-implementation.

Thermal insulation for outdoor heating pipes

A variety of heaters makes it possible to choose exactly the one that fit best way for a specific place of application (outdoors, in the ground, in the basement, in the attic) and budget.

The selection of a heat insulator is carried out taking into account the following factors:

• diameter of the pipe of the heating system;

• operating conditions (location of the heating system);

• average heating temperature of the coolant;

• the thermal conductivity of the insulation (the lower the better);

• water absorption index. Shows the ability of the insulating material to perform its functions in a humid environment;

• resistance to combustion, biological and chemical activity, exposure to ultraviolet radiation and other environmental factors;

• life time;

• ease of installation (with the condition of ensuring sufficient tightness);

• price.

How to insulate heating pipes on the street with your own hands

To choose the right pipe insulation, you need to know what types of thermal insulation for heating pipes exist, and what are the features of each of them.

Classification of heat-insulating materials for heating pipes

1. According to the installation method:

• rigid sheet insulation. These include: polystyrene foam and polystyrene foam. Despite the high thermal insulation properties, the installation of such heaters is quite complicated in terms of ensuring the tightness of the insulation;

• roll insulation. Among them: polyethylene (used as an additional component of insulation), foil penofol, cotton wool (mineral and glass wool). Application roll materials requires the arrangement of their reliable fastening to the pipe;

• segment (casing) heaters. There are two types of such heaters: rigid - shells made of expanded polystyrene, polyurethane foam (PPU) or polystyrene, and soft - polymer pipes. The advantage of segmental materials is that they keep their shape perfectly, are easy to install and provide the required level of tightness of the fit of the heat-insulating material to the heating pipe;

• sprayed heaters, incl. thermal paint. Penoizol has proven itself as a spray gun, because it allows you to isolate even small gaps. Thermal paint has the same property. The only disadvantage of these materials is that they are quite expensive and their self-application is problematic.

Thermal insulation of heating pipes with hard, soft and sprayed heaters

2. By type of insulation:

• polystyrene and expanded polystyrene. They have the best characteristics in terms of maintaining the initial temperature of the coolant. Their use in the form of a shell simplifies installation and provides reliable protection of the system;

Thermal insulation for heating pipes - foam shell Thermal insulation material for heating pipes - polystyrene foam and polystyrene foam

• wool (mineral, glass wool). It can be used as a roll and as a sectional material. Regardless of the type and configuration, cotton wool insulation for heating pipes has a significant drawback, which is that cotton wool is hygroscopic. Those. it needs additional protection from moisture. When wet, cotton wool loses its properties. Therefore, sections often have additional protection in the form of a foil layer. But cotton wool is great for thermal insulation of pipes in the basement or in the attic.

Heating pipe insulation technology

The choice of pipe insulation and the method of its installation is influenced by the location of the pipeline.

Insulation of heating pipes on the street

External thermal insulation of pipes - the most hard way insulation, since in the open air not only pipes need protection, but also the insulation itself. For outdoor installation, non-hygroscopic materials are used, or others, but reliably protected from moisture by a film, casing.

In addition, it is advisable to use the densest and thickest insulation on the street. Another requirement is the use of material that is resistant to ultraviolet radiation, bad weather and mechanical damage.

Insulation of heating pipes in an unheated room

Basement, cold attic, boiler room - a feature of such premises is the absence of heating radiators. But since the pipes are filled with a heat carrier and located in an environment with minimal humidity, there are no special requirements for either the heat-insulating material or its thickness.

Thermal insulation of heating pipes in an unheated (cold) room

Insulation of heating pipes underground

The specifics of installing heating pipes underground is that they must be laid below the freezing level of the soil, and this is a depth of one and a half to two meters. If this requirement is not adhered to, the coolant will be strongly cooled until it passes through the heating main located in the ground. In order to reduce heat loss, you need to take care of high-quality insulation of the underground pipeline.

The masters say that the best solution in this case would be to use a cable heating system for pipes. But due to the high cost, users prefer reinforced thermal insulation of heating pipes.

Good insulation of heating pipes underground implies the fulfillment of the requirements:

• isolation of the insulation from the moisture that is in the soil;

• exclusion of the possibility of deformation of the insulation, tk. in this case, its properties are reduced. This is especially true for soft thermal insulation materials;

According to reviews, the best solution is the thermal insulation of heating pipes using PPU shells.

Note. Users recommend for pipes that are laid above the level of soil freezing to use a combined insulation system, namely: a combination of wool and rigid PPU shell with protective coating fiberglass. Ideally, even at the laying stage, use factory-made multilayer pipes in PPU insulation.

How to insulate heating pipes with your own hands

The sequence of actions in the form of step-by-step instructions:

• calculation and purchase of thermal insulation material;

• wrapping the pipe with foil tape or foil. The foil acts as a heat reflector;

• installation of insulation around the pipe. Sectional hard (casing) or soft insulation is simply “put on” on the pipe. Concerning soft materials, then they need to be cut into blanks, equal in width to the diameter of the pipe. Then wrap it around the pipe and fix it with tape, wire or plastic clamps. Hard insulation is the hardest part. From it you need to create a box around the pipe (or use pipe shells of the appropriate diameter);

• inspect the insulated pipe for the presence of "cold bridges" and eliminate them;

• fix the heat-insulating material on the pipe using plumbing or metallized tape;

• if necessary, cover the heat-insulating material with a protective material (film) and seal the joints with adhesive tape.

The cost of insulating heating pipes, despite their initial value, quickly pays off by saving on bills for heating the house.

Insulation of heating pipes - thermal insulation for heating pipes

Thermal insulation for water supply and heating pipes

Thermal insulation for pipes is used primarily to reduce heat loss in heating systems, inevitable after the onset of cold weather. Tellingly, such thermal insulation is necessary not only in order to maintain the required temperature indicator in the heating main, but also in order to prevent the accumulation of condensate on the pipe walls and the insulating material itself, freezing of the working fluid during stagnation, and also to slow down the rusting process of iron elements. Due to all this, the operational life of the system itself is increased.

How to choose insulation material for pipes

Due to the peculiarities of the domestic climate, high-quality thermal insulation is necessary not only for centralized heating mains, but also for individual networks. There are a number of factors that determine the choice of one or another insulating material, here they are:

• operating conditions of the system;
• the diameter of the pipeline itself;
• heating temperature of the working fluid.

The key factor in this case can be considered precisely the diameter, since the type of insulation used largely depends on this. So, modern manufacturers offer semi-cylindrical, cylindrical and rolled heat insulators.

Thermal insulation for pipes

Note! As for rigid cylinders and semi-cylinders, they are used in lines of small diameter. This kind of material is equipped with grooves that simplify the installation procedure.

In addition, segments made of plastic or mineral wool are used for insulation. In general, hard insulation is good because it is not only resistant to elevated temperatures or low moisture absorption, but also because it has a permanent, clearly geometric shape, which provides high-quality protection against mechanical damage.

In order to find out which of the heaters to purchase, you should familiarize yourself with the key materials and their areas of use.

Mineral wool

Materials made from mineral wool are very popular because of their effectiveness. As for the advantages of insulation, they are as follows:

• non-toxicity (this is one of the safest building materials);
• sufficiently high heat resistance (the material can withstand up to 650 degrees); which is typical, when heated, it retains its original thermal insulation and mechanical parameters;
• low degree of moisture absorption (during the manufacturing process, mineral wool is treated with special impregnations);
• chemical resistance to acid, solvent liquids, oily solutions and alkalis.

This material - perfect option for insulation of supply lines hot water and heating (not only in residential, but also in industrial facilities). Often, mineral wool is used for thermal insulation of pipes that are subject to regular heating (this can be, for example, a stove chimney).

We also note that mineral wool is produced in several varieties at once, let's get acquainted with them.

1. Stone wool - it is made from rocks, which is why it is also called basalt.
2. Glass wool is made from cullet or staple fiber made from quartz sand. Such a heater differs from that described in that it is not so heat-resistant, and therefore the scope of its use is not so wide.

The approximate cost (with dimensions of 30-18 mm) is about 46 rubles per linear meter.

glass wool

Fiberglass heat insulator is produced in rolls 155-200 centimeters long (the thickness can vary from 3 to 4 microns). It is characteristic that the material has a low density, which means that it cannot be used for highways that heat up over 180 degrees.

This thermal insulation for pipes is suitable for ground-type communications. Among its advantages it is worth highlighting:

• long service life;
• vibration resistance;
• chemical resistance. and biol. substances.

The average market cost is about 700-800 rubles per pack(500x122x10).

Polyurethane foam insulation

Polyurethane foam insulation is a construction with a fairly rigid shape; in fact, it consists of walls and ribs. Let us devote a few words to the production of this material: in its manufacture (if we are talking about industrial scale) uses the so-called "pipe-in-pipe" technology. This insulation is also called a thermal insulating shell. It is not only durable, but also reliably retains thermal energy inside the line.

In addition, polyurethane foam has the following advantages:

• non-toxicity;
• the ability to withstand various weather conditions (therefore, the material is suitable for outdoor use);
• lack of smell;
• resistance to different kind chemicals;
• absolute safety for health;
• excellent dielectric properties;
• high strength (the pipeline will be protected from breakage caused by external mechanical loads).

As for the disadvantages, there is only one in the polyurethane foam heat insulator - this is a high price ( approximately 345 rubles per meter).

Foamed polyethylene

Let's make a reservation right away that it is this heat insulator that has occupied a leading position in the market in recent years, today it is used almost everywhere, not only in heating systems. In fact, this is a ready-made shell, made in the form of a pipe, as much as possible "enveloping" the highway and protecting it from various kinds of external influences. Anyone can handle the installation of polyethylene foam - this does not require any specific skills and knowledge. First, the polyethylene sheath is cut along the existing seam (after installation, this seam should be glued back).

Excellent thermal insulation characteristics are provided by the foam structure of the material. This polyethylene is, in fact, a thermos, because it (the material) can also be used in freezing equipment.

Average market price - from 105 rubles per running meter.

Other insulation materials

In addition to the heaters described above, other thermal insulation for pipes is also sold on the market. Let's get acquainted with the main varieties.

PPU shell for pipes

Earlier we talked about the technical characteristics and features of the PPU shell for pipes, in addition to this article, we advise you to read this information, read about it here

Option one. Styrofoam

This heat insulator is made in the form of two halves, which are interconnected during installation. To do this, the "thorn-groove" technology is used, which eliminates the possibility of the appearance of cold bridges in the material.

Option two. Foam glass

Completely safe material, which consists of glass with a cellular structure. This is a non-shrink version of the insulation, characterized by durability and strength. It does not burn, easily withstands various chemical influences, and is resistant to the invasion of rodents.

Note! Even a beginner can cope with the insulation of the pipeline with foam glass, and there is still a guarantee of a long service life.

Option three. Penoizol

By their own technical specifications remotely resembles foam, but it is only sold in liquid form. During the processing of highways, no “gaps” remain, and the entire system will be quite tight after drying.

Option four. Styrofoam

Among distinguishing features This material is distinguished by low thermal conductivity, resistance to fire, slight moisture absorption, heat resistance, long service life (about fifty years) and excellent noise insulation qualities. In view of all this, polystyrene is an indispensable heat insulator that can be used on an industrial scale.

Thermal insulating paint

By the way, this is a new innovative development, which Russian scientists have created to everyone's pride. This paint contains:

• foam glass;
• perlite;
• ceramic microspheres;
• a number of other thermal insulation components.

If you cover the pipeline with such paint with a layer of at least 2 millimeters, then the results will be the same as with insulation with several layers of foam or mineral wool. This paint is harmless to the body and nature as a whole, it has practically no smell, therefore, there is no need for ventilation. With the help of a heater, reliable protection of pipes against rust is created, the material itself does not warm up under the influence of high temperatures. Apart from household purpose, the paint can also be applied in industrial and manufacturing environments.

Note! The heat insulator is produced in the form of an aerosol, due to which the installation procedure is noticeably simplified. In this case, the most inaccessible of places are subject to painting.

All of the above heaters have a different structure and different parameters, but the function is one - the protection of domestic and industrial pipelines. After installing the heat insulator, heat losses during the circulation of the working fluid are significantly reduced. All this allows you to reduce heating costs, which means that there is also an economic component.

How is the installation of a heat insulator on pipes

The specific insulation procedure depends on which of the materials was chosen. Although in general terms, the algorithm of actions is the same and consists of three main stages.

Stage one. So, the thermal insulation for the pipes is purchased, you can get to work. At first, before the installation begins, the pipes are pasted over with foil tape, and it is extremely important that this be done in a spiral.

Stage two. Insulating material is installed on the pipes. After that, with the help of special adhesive tape (although in this case it is quite possible to use plumbing), the material is attached to the pipeline and wrapped as tightly as possible.

Note! Winding the insulation with adhesive tape is mandatory, otherwise groundwater will penetrate into the gaps formed, which will negatively affect the functionality of the entire highway.

Stage three. Upon completion of the installation work in without fail check is made. Everything, it remains only to check the quality of the insulation layer in action!

The pipeline is frozen - how to warm it up?

As we noted above, modern assortment insulation materials is huge, so you need to try your best so that in the future you do not encounter the problem of freezing the pipeline.

Note! Thanks to a well-equipped heat-insulating layer, frost will never be able to get to the working fluid moving through the pipeline.

But it happens that for some reason you did not take care of good insulation. What to do in this case? In any technical handbook you can find information that pipelines must be laid - a must! - taking into account the level of soil freezing. This means that if you did not have the opportunity to lay the main line below this "waterline", then it (the main line) had to be insulated.

And if all these requirements are not met, then a situation may arise when, due to a sudden frost, the water in the pipeline completely freezes. Speaking specifically about metal pipes, then in such cases they often burst; plastic products do better, but the working fluid will still not pass through them.

Now we will consider what measures should be taken in order to get rid of the ice. If the metal-plastic heating pipes, then there is one effective option solution to the problem: a smaller pipe must be inserted into the frozen pipe (although a rigid hose may also work) and hot water can be supplied through it until the ice is completely melted. But all this is preceded by the search for a frozen section of the highway. This can be done as follows: gradually bend the plastic pipe until a characteristic "ice" crackle sounds. It is in that section of the network where you heard the crackling that you need to heat up.

There is an alternative solution to the problem - with the help of an ordinary household hair dryer (if it is not possible to use a building one).

If the line is frozen for a long time and there is no way to warm it up, you can temporarily stretch out new heating pipes insulated with polyethylene foam and use them until the ice melts on its own.

Insulation for heating or water supply pipes - an overview of the best materials with characteristics and cost

Pipes located in unheated rooms need protection against freezing. Whatever material they are made of, their thermal conductivity is high, so freezing occurs quickly. To avoid unnecessary problems, use pipe insulation, which will create reliable insulation for the pipeline from frost and even noise insulation due to its noise-absorbing qualities.

Thermal insulation for pipes

There are many companies on the Russian market that produce structural elements to reduce heat transfer. You can choose products made from different materials, choose right size and characteristics suitable for your communications. Thermal insulation of pipes can be carried out from several types of protection, such as polyethylene or foam.

How to choose pipe insulation

To choose the right insulation for water pipes and protect yourself from problems, you need to pay attention to three main factors: location (apartment, attic, in the ground, in the sewer, outdoors), ease of installation, price. All types of products are easily installed independently, but universal in all characteristics - polyethylene.

When it is important to reduce heat absorption, choose foil insulation for pipes. Expanded polystyrene is fragile, but suitable for work anywhere. Basalt material is easy to install, has good performance, but is expensive. If you want to quickly insulate the system, but other methods are not suitable, choose a thermal paint that is easy to apply, looks beautiful and protects well.

Insulation for pipes - a description of thermal insulation materials for heating, plumbing and sewerage

It is necessary to protect from the cold not only building structures, but also engineering communications. Proper insulation of heating pipes reduces heat loss, reduces the risk of freezing if hot water circulation has stopped for a long time due to accidents and repairs. The consumption of fuel and energy resources increases along with monthly utility bills.

Requirements for thermal insulation of heating pipes

Technical requirements for thermal insulation of pipelines are established by SP 61.13330. During operation, it is exposed to influences of a different nature - mechanical, chemical, thermal, humidity, so it must be not only energy efficient, but also reliable, durable, and safe.

Characteristics of materials that are taken into account when choosing:

• Thermal conductivity, density - determine the thickness of the insulation layer, the load on the pipe, its supports.
• Heat resistance - determines the invariance of the initial properties in contact with a hot surface.
• Elasticity, compressive strength - are responsible for the stability of the shape and structure during caking, laying in the ground.
• Water resistance - eliminates the absorption of water, allows you to maintain thermal insulation properties.
• Biostability, resistance to aggressive environments are important for long-term operation.
• Combustibility, content of harmful substances - must meet sanitary and hygienic requirements, fire safety standards.

From a practical point of view, convenient, simple installation is important. It saves time, eliminates additional costs for installation materials.

Functions of insulating materials

Heating pipelines are insulated for any type of laying - underground and aboveground on the street, in technical rooms of apartment buildings, private houses, industrial, public buildings. The tasks of materials and structures do not depend on the location of communications.

Thermal insulation for heating pipes must:

• Maintain the temperature of the coolant to ensure comfort in residential and working premises.
• Reduce heat losses in the pipeline, maintain them at an acceptable level, reduce fuel or energy costs.
• Ensure safety in contact with the surface, as the temperature of hot water in the pipes reaches 1050C.
• Protect the system from freezing, corrosion, deformation, damage, extend its maintenance-free service life.

Properly selected and installed insulation performs all functions during the estimated service life.

Types of materials for thermal insulation of heating pipes

Technical solutions for pipe insulation differ in design, materials and characteristics.

Mineral wool

Technical insulation made of basalt rock wool for insulation of high-temperature pipelines is produced in coiled cylinders, slabs and mats, including those with one-sided foiling. It is chemically inert, bioresistant, non-combustible, has a thermal conductivity of about 0.04 W / m * K and a density of 100-150 kg / m3.

The materials are effective, affordable, but have drawbacks. The use of mineral wool insulation for insulating heating pipes in attics, basements, technical undergrounds is limited due to high humidity. The tendency to caking, the absorption of moisture leads to a violation of the structure, wetting, a rapid deterioration in heat-shielding properties.

Styrofoam and expanded polystyrene

Heat-insulating materials from extruded polystyrene foam and polystyrene are made in the form of plates, segments in the form of half-cylinders. They are used to protect house heating pipelines, to assemble a closed or U-shaped box when laying a pipeline in the ground.

The insulation has a density of 35-40 kg/m3, a thermal conductivity coefficient of about 0.035-0.04 W/m*K, and low water absorption, does not rot, and is easy to install. The disadvantages include combustibility, a narrow range of operating temperatures from -600 to + 750C. Pipes must be treated with an anti-corrosion compound before installation in the ground; with open laying, the insulation must be protected from UV rays.

polyurethane foam

For insulation of heating pipes, PPU shells with and without foil coating are used. The material is characterized by low thermal conductivity of 0.022-0.03 W / m * K and water absorption due to the closed cellular structure, high strength, long service life, does not rot, is quickly mounted. Uncoated shells are used only indoors, as polyurethane foam is destroyed by UV rays.

Insulation of large diameter pipelines can be performed using sprayed polyurethane foam insulation. It has an increased density and fire resistance, significantly reduces heat loss due to a continuous coating without "cold bridges".

Foamed synthetic rubber

rubber technical thermal insulation produced in rolls and tubes. It is non-combustible, environmentally friendly, resistant to chemical and biological influences, has a density of 65 kg/m3 and a thermal conductivity of 0.04-0.047 W/m*K.

The materials are used to insulate pipelines in rooms laid above and below ground; they may have an aluminized coating to protect against mechanical damage and UV rays. The main disadvantage is the high cost.

Foamed polyethylene

Thermal insulation for heating pipes made of foamed polyethylene with an elastic porous structure is used in any conditions, does not absorb water, maintains a low thermal conductivity of 0.032 W / m * k with temperature changes. It is available in the format of tubes, rolls, mats, easy and quick to install.

The material is used indoors, heating points, when laying pipes in the open air, in the ground. For above-ground installation, it is necessary to provide a cover layer, for underground - a casing.

Comparison of the characteristics of heating pipe insulation

The advantages of using polyethylene foam for thermal insulation of heating pipes are obvious. Foamed polyethylene insulation wins in operational, physical and economic properties. It is versatile, energy-efficient, retains heat-shielding properties throughout its service life, and is used at medium and low-price facilities due to its affordable cost.

Withstands temperatures over 1000°C.

ROCKWOOL insulation is extremely fire resistant. It contributes to the localization of the fire and prevents its spread. In addition, it does not emit toxic substances and is safe for isolating children's rooms.

thermal insulation

Save energy by maintaining optimum temperature and indoor microclimate.

This makes working and living conditions healthier and more comfortable, improving people's quality of life - especially in urban environments. Temperature stability can significantly reduce heating, cooling and ventilation costs, as well as reduce greenhouse gas emissions.

Soundproofing

Isolation, absorption or correction of sound.

The city needs good infrastructure (roads, railways and trams, airports), but it is sometimes too noisy. Vibration, traffic noise - not to mention anthropogenic noise pollution - lead to serious negative consequences for well-being, especially in densely populated areas.

Durability

Improved performance characteristics and increased stability at lower cost.

In cities experiencing a shortage of free land, a growing number of people work and live in high-rise buildings. Such structures can be a brilliant solution to the problem of providing a growing population with safe and durable housing.

Aesthetics

A harmonious combination of performance and aesthetic qualities.

When people live or work in a beautiful place, it increases their sense of comfort and motivation. An environment in which people enjoy their time strengthens social bonds and makes the surrounding area safer and more livable.

Water resistance

Efficient handling of the most valuable resource.

Traditional food production methods are losing ground in the face of population growth, and climate change is increasing the need for flood protection. Stone wool products can be designed to absorb or repel water as needed, and can also be used to recycle water in greenhouses, helping to address a range of water management challenges.

Environmental friendliness

ROCKWOOL sustainable products bring out the power and naturalness of natural stone.

Stone is one of the most common materials on earth; however, we must make better use of our planet's resources. We have developed technologies that allow us to use waste from other industries as alternative raw materials.
