How to insulate a water pipe in a private house

Types of heat-insulating materials for pipes

Styrofoam

This is a very popular material for warming plumbing systems.

Let's take a look at some of its benefits:

• much more often used as a heater for water pipes and is produced in the form of finished parts (shells) of different diameters;
• can be used both independently and in conjunction with other materials (for example, waterproofing);
• for its installation, the manufacture of mounting trays is not required;
• It is used both in houses and for outdoor laying of engineering networks.

The installation instructions for this heater are extremely simple:

• the required number of foam shells is purchased to insulate pipes of a certain diameter;
• two halves are put on the water supply section and secured with a special lock;
• for additional strength, the insulation can be sealed with adhesive tape;
• at the docking points, the insulator must be overlapped in order to avoid the occurrence of cold bridges.

Foamed polyethylene

Such material is less common, but more convenient for arranging thermal insulation. It is used as a heater for sewer pipes and other similar networks.

Foamed polyethylene has the following undeniable advantages:

• flexibility;
• long term of work;
• elasticity;
• good thermal insulation features;
• high sound absorption coefficient;
• environmental friendliness;
• affordable price.

Alternative materials

In addition to the above, there are other materials that are used to isolate water transport systems and as a heater for chimney pipes.

Material	hell
Fiberglass	A very good insulation for polymer pipes, which has a low density. But it requires additional waterproofing measures, which increases the price and installation time.
Basalt insulation	It has a low coefficient of thermal conductivity and an additional foil protective layer. Supplied as ready-made parts of a certain diameter (like foam), it is easy to install and does not require preparatory work before installation. The disadvantage is the high price.
Penofol	A fairly new insulation with an additional protective layer of iron foil. Represents polyethylene foam of different density. Sold in rolls, which facilitates its installation on pipes of different diameters, laid in hard-to-reach places.
polyurethane foam	This is a very effective insulation for pipes, which can significantly reduce heat loss in the heating system. It is mounted on a polymer pipe at the manufacturing stage.
Penoizol	It has characteristics similar to foam insulation. Sold in the form of a special mixture, which is applied to pipes using special devices. Has sealing properties. Great for processing outdoor pipes.

Thermal insulation paint

This material is easy to apply and does not completely increase the size of the pipeline.

Despite this, heat-insulating paint has the following characteristics:

• has a low coefficient of thermal conductivity;
• protects iron parts from rust;
• prevents liquid condensation on the pipe surface;
• retains its properties at extreme temperatures;
• has a long service life;
• applied to the pipe with a brush or spray;
• it is possible to cover pipes in hard-to-reach places;
• enhances the appearance of the pipeline.

At the end of hardening, the composition provides the same level of thermal insulation as simple mineral wool.

Features of the choice of insulation

Naturally, the choice of insulation is carried out depending on where the pipes are laid and what the conditions are there. Also, insulation also depends on whether the residence is seasonal or permanent.

For example, if you want to insulate pipes in the country, where you mostly visit in the summer, then it is better to use glass wool. However, if you use the house as a temporary home, then choose automatic or semi-automatic heating systems, for example, the same heating cable. After a long absence of water, you can always warm up or turn on the pump.

Regardless of the conditions in which you plan to install insulation, consider the following:

• it must be of high quality;
• choose material depending on the frequency of use of water supply;
• installation must be carried out very carefully and meticulously, do not neglect the instructions.

Drinking HDPE pipe

It is made of polyethylene, the compounds of which are formed in a pressure chamber with a vacuum, into which argon is supplied with raw materials. Hence the name "Low-pressure polyethylene", but, despite the specificity of the name, HDPE pipe can withstand pressure from 10 to 100 atm. The HDPE pipe contains up to 70% -80% polyethylene, due to which it is rigid and has temperature limits, only 70 degrees Celsius. As a result, such a limitation by itself allows the pipe to be used only for supplying cold water with a temperature not exceeding 30 degrees Celsius. However, despite the narrow range of its characteristics, this type of water supply is widely used to supply water to a house from a well. It is used for plumbing in the country. Of course, due to the specificity of the material, such a pipe is afraid of ultraviolet radiation - the structure of the molecular bonds of the material begins to gradually break down. Such a minus reduces the life of the pipe and can lead to a pipe break in this place.Therefore, on the street, such a pipe is laid in the ground or in special channels where there is no access to sunlight. The service life of such a pipe is guaranteed up to 50 years, however, using such a pipe in the open access of sunlight, the service life is reduced to 15-20 years.
The pluses include ease of installation and strength of fitting connections, as well as the frost resistance of the pipe. For example, you forgot to drain the water from the system at the end of the season, then there is no point in worrying. Turning into ice, the liquid will expand, and due to its elasticity, the pipe will expand and remain intact. Exceptions include fittings and taps - there is nothing to expand.
One of the characteristics of the pipe can be attributed to its radial expansion, which is up to 30%.
More about types and varieties HDPE pipes You can read our article.
The plumbing is connected HDPE pipes in a manner similar to the connectionCOLLET».
The connection is untwisted, a conical collet-ring, a sealing conical ring are pulled out of it. All this is put on the pipe, and the pipe is inserted all the way into the fitting itself. The fitting has a sealing rubber ring, which is a gasket. Then a sealing cone ring is inserted, a plastic collet is pulled behind it and the connection is tightened with a cover. By tightening the connection, the pipe is clamped and tightly rests against the walls of the fitting, and the rubber ring, expanding, closes all the micro-slits that can let fluid through. It makes no sense to tighten such a connection much !!!!
         The mistake of most is that they, like with an iron pipe, pull so hard and as a result they break the thread or break the connection itself, or the rubber ring breaks. To tighten the fittings, it is necessary to use a special “Key for HDPE fittings”.
Unlike most types of water supply HDPE pipes are also used for supplying central water supply, such water supply system does not rust and is durable. In addition to push-in connections to HDPE pipes and fittings applied heat seal. There is a huge variety of fittings, both flanged and welded connections, as well as threaded, compression, tie-ins into the pipe. This allows you to expand the range of applications of this type of pipe. At cost, water supply from such a pipe can be equated to a water supply system made of polypropylene, however, due to the fragility of polypropylene at low temperatures, it is better to choose HDPE pipe.
Also, among drinking HDPE water supply, technical HDPE pipe. Such a pipe is softer due to the polyethylene content of only up to 30%. According to the properties of the HDPE material, it also corresponds to drinking, but the use of such a pipe for drinking water supply is not desirable. Since 70% of the material of such a pipe is recycled, which may contain toxic plastics.

What can be used

In principle, any material that will be listed below can be used to insulate a water pipe. But the choice should fall on the one that will be most suitable for specific conditions.It may not meet absolutely all the requirements listed above, and this is not always necessary.

Mineral wool and polyethylene foam

One of the options that has been used for a long time and is constantly being improved is mineral wool. There are several varieties of it. Glass wool is made from glass, its share is about 35% (usually recycled glass containers, etc.), soda ash, sand and other additives. Therefore, it can be called sufficiently environmentally friendly. Its positive aspects are:

• minimum thermal conductivity;
• ease of installation;
• light weight;
• ease of transportation;
• not food for rodents;
• noise protection.

Of the minuses can be noted:

• poor resistance to moisture, which leads to loss of thermal insulation properties;
• the need to use personal protective equipment during installation;
• the fiber is easily damaged and torn with little effort;
• shrinkage may occur over time;
• resistance to fire.

Basalt wool

A peculiar subspecies is basalt wool. It is made from stone battle. In addition to all the above advantages, one can single out resistance to high temperatures, as well as immunity to moisture.

foamed rubber

Foamed rubber is a synthetic product that has appeared on the market not so long ago. It was developed specifically for the insulation of pipelines indoors and outdoors. Its characteristics:

• high elasticity;
• resistance to high temperatures;
• moisture resistance;
• ease of installation;
• vapor tightness;
• self-extinguishing when exposed to an open flame.

If we talk about the minuses, then this is most likely only the complexity of delivery, because it takes up a fairly large volume with a low weight.

Insulation for pipes polyethylene foam

Polyethylene foam is often used as a substrate for various floorings. But some of its types are designed specifically for pipeline insulation. The choice of masters falls on him because he:

• does not support the development of bacteria and fungi, which is very important for a humid environment;
• easy to install;
• has a small weight;
• UV resistant;
• fireproof;
• does not require special skills during installation.

With prolonged use, the material may shrink to a certain extent, which reduces its initial performance. In addition, there are certain problems when sealing seams. It is very difficult to achieve a perfect fit in some cases.

Styrofoam

Penoplex and polystyrene foam have a lot of similar properties. They are derivatives of the polymer component. This means that they practically do not interact with organic substances. These materials:

• are easy to install;
• have a small weight;
• have zero heat capacity;
• resistant to moisture;
• characterized by compressive strength.

At the same time, the products are very unstable to open fire. Rodents are very fond of harming such heaters.

Foamed polyurethane

The shell made of foamed polyurethane is a product in the form of semicircles, which are put on like a cover on a pipe. Usually on top it is covered with a protective layer of waterproofing. Use it based on:

• ease of selection for a specific diameter;
• lack of thermal conductivity;
• light weight;
• assembly in the form of a constructor;
• the possibility of multiple use;
• the possibility of carrying out work on insulation even in winter.

The negative aspects are: sufficient transport costs, as well as a maximum temperature limit of 120°C.

Insulation paint

A relatively new, but quite interesting development is insulation with a special paint. Even a small layer of it has good insulating properties. If it is increased several times, then the losses will be significantly reduced. This product:

• easy to apply on surfaces of any shape;
• has excellent adhesion to metal;
• not affected by salts;
• endowed with anti-corrosion properties;
• eliminates the formation of condensate;
• no additional load on the pipes;
• after coating, all valves or revision units remain freely available;
• ease of repair;
• high temperature resistance.

Of the negative sides, one can single out the need for additional insulation in case of severe freezing of the soil or the external location of the water pipes.

Thermal insulation for water supply pipes

It is not difficult to get confused in a wide range of thermal insulation materials. To choose the best option, you need, at a minimum, to know the main types and types, key characteristics and features.

Thermal insulation of water pipes is carried out by various heaters, which are grouped below (in the form of classification) according to the principle of unity of insulation technology.

Rigid insulation

This category includes polystyrene, expanded polystyrene (2560-3200 rubles / cubic meter) and Penoplex (3500-5000 rubles / cubic meter), thermal insulation properties and price depend on density.

Laying water pipes in a foam box

Roll insulation

This segment includes: polyethylene (as an additional material), foil foam (50-56 rubles / sq.m.), cotton wool (mineral (70-75 rubles / sq.m.) and glass wool (110-125 rubles / sq.m.) ), furniture foam rubber (250-850 rubles / sq.m., depending on the thickness).

Insulation of water supply pipes with roll insulation is also fraught with difficulties, which lie in the hygroscopicity of the material. Those. the insulation loses its properties under the influence of moisture, which means it has a narrower scope, or needs additional protection. Plus, it is necessary to think over the method of attaching the insulation to the pipe.

Basalt heat-insulating mats and foam rubber for insulation of water pipes

Segment (casing) heaters

The casing-insulation for pipes is the most progressive variant of thermal insulation of the pipeline. The water pipe insulation shell provides maximum tightness and, as a result, creates a reliable heat-insulating layer.

There are varieties of segment heaters:

Styrofoam shells for insulating water pipes are rigid (a heat-insulating casing for pipes is a shell made of expanded polystyrene (PPU) or foamed polystyrene. The price is from 190 rubles / m.p., depending on the thickness and diameter of the cylinder);

Sprayed insulation (PPU)

The peculiarity of insulation by spraying polyurethane foam is that thermal insulation is applied to the surface of the pipe, providing 100% tightness (the cost of components for polyurethane foam filling is from 3.5 euros per kg).

The number of components is determined by the thickness of the fill, the work is paid extra). On average, the cost of insulation by spraying polyurethane foam is 15-20 dollars / m.p.

Sprayed insulation also includes heat-insulating paint for pipes. You can apply it yourself, because. thermal paint is sold in cans in the form of an aerosol.

20 mm paint layer. replaces 50 mm basalt wool insulation. In addition, it is the only material that is not susceptible to damage from rodents.

Insulation of water pipes by spraying polyurethane foam (PUF) Water pipe insulated with polyurethane foam (PUF)

When choosing a heat-insulating material for insulating water pipes, you need to take into account the following factors:

pipeline installation site

Insulation of pipes laid on the ground and located underground is carried out in different ways, even when using the same materials (it is also important to take into account pipes laid to or below the freezing level);
pipeline operation frequency. For example, in a country house that is not intended for permanent residence, it is enough just to avoid a pipe rupture

To do this, a receiver is installed or the water pipe is insulated with a cable. But in a private house it is necessary to ensure the supply of water all year round. Here, the choice of insulation should be approached more carefully;
indicator of thermal conductivity of pipes (plastic, metal);
resistance to moisture, burning, biological activity, ultraviolet, etc. determines the need to protect the insulation from these factors;
ease of installation;
price;
life time.

Ways to insulate water pipes

So that the frost does not damage the water pipes in a private house / cottage / cottage, you have to worry about their thermal insulation in advance.

It is important even at the stage of laying communications to consider options for insulating pipes, and not only water pipes. If this is done in a timely manner, the costs will be minimal.

There are a lot of options for pipe insulation - it is important to choose high-quality material among the mass of offers, not focusing too much on price. The cheapest option is money thrown to the wind. Among the methods of insulating a pipeline for supplying water to a house among homeowners, the most popular are:

Among the methods of insulating a pipeline for supplying water to a house among homeowners, the most popular are:

• stretch the pipeline 0.5 m below the freezing level;
• use a heating cable;
• insulate with heat-insulating material;
• provide an air gap;
• buy a finished factory pipe;
• apply multiple methods.

Most often, more than one method is used. So, if the water pipes are deep, then the area responsible for the entrance to the house still needs to be insulated. Therefore, the most optimal option is selected for it in order to secure the local water supply system.

The depth of the pipeline depends on the region. To find out, you can use special reference tables by finding your region or check it empirically

The heating cable is widely used due to the ease of installation and the high-quality performance of the functions assigned to it.

Depending on the type of installation, there are 2 types of cable:

• outer;
• interior.

The first is mounted on top of the water pipe, and the second - inside. It is securely insulated and made of safe materials. It is connected through a heat shrink sleeve to a regular cable with a plug or to a machine.Read more about heating cable for plumbing.

The heating cable comes in different capacities. Most often found between 10 and 20 watts

There are a lot of thermal insulation materials on the market. They all differ in their properties, quality, price, complexity of installation and service life.

Which one to choose depends on the specific situation.

Among the heaters, polyethylene and polyurethane foam semi-cylinders - shells are especially easy to install.

The air gap method is also often used. It is a water pipe placed in a cheap smooth plastic or corrugated pipe of a larger diameter.

Inside there is free space for the circulation of warm air coming from an insulated basement or heated in another way.

Warm air perfectly protects the water pipe from freezing. Although often it is additionally insulated with polypropylene or other material

Another option is to buy ready-made insulated pipes of factory origin. They are sold fully assembled.

They are 2 pipes of different diameters placed inside each other. Between them is a layer of insulation. Often this method of insulation is called pre-insulation.

The option with ready-made pipes does not always satisfy the needs of a particular user - the diameter, type of material and cost can become a real problem for their purchase

The use of several methods of thermal insulation of pipes is due to the fact that all methods are imperfect and it will not be possible to apply them in all cases. The conditions of use in various households located in all regions of the country are radically different from each other.Therefore, you have to choose the option that suits your specific requirements.

Methods for insulating underground water pipes

There are two main ways to insulate water pipes:

• by installing a heater. Insulation occurs partly due to air, since the pipe is also saved from freezing by warm air going from the bottom up, and at the top the material closes the structure from the cold, for this it is contained in a cylindrical insulation;
• by installing a heating cable, sensors and warning devices.

There is also a third, less common way of warming with high pressure. To do this, use a special receiver to build pressure from a submersible pump, and cut into the water supply. But here it is necessary to install a check valve.

To make sure that the underground water pipe is well insulated, the insulation must be laid correctly and the trench must be deep.

Do-it-yourself pipe insulation: work progress

The pipe must be wrapped with material and fixed with adhesive tape. On top we place a protective layer of roofing felt or other durable material.

The parts of the insulation material must be connected on the pipe by means of joints that are cut out along the edges and additionally fixed with adhesive tape.

The most reliable material for heating pipes underground is a heating cable, despite its high cost. It can be installed even at a depth of 50 cm to 2 m, which saves you from having to dig a deep trench.

The cable should be wrapped around the pipe every 10 cm, and after 15 cm it should be fixed with adhesive tape. From above it also needs to be covered with insulation.In some cases, the cable is placed not only outside the pipe, but also inside, but it is extremely difficult to do it yourself.

Install temperature sensors in an amount of about 3-4 pieces along the length of the water supply. They will help to establish a system of automatic heating and manual control. Such a system will provide you with water regardless of the season.

The cost of a heating cable is about 500 rubles per meter, and it consumes from 10 to 20 W of energy. If your plumbing is not too long, this will be the best solution for you.

You can also establish an air insulation system, but here you must first create special conditions for the plumbing system. So, in this case, the pipes must move to others with a larger diameter, this creates the so-called air cushion. Cold air does not reach the water pipes from the top, and below they are heated by the heat of the earth. If you have chosen this method of insulation, you will need to dig a trench of at least a meter, and also apply not only insulation material, but also additional pipes.

And with this method of pipe insulation, the water flow in the event of a malfunction will be difficult to repair. But on the other hand, this method is effective and economical in terms of the cost of materials and work.

Heating

When planning a winter water supply system, you need to keep in mind that insulation only helps to reduce heat loss, but cannot heat. And if at some point the frosts turn out to be stronger, the pipe will still freeze. Particularly problematic in this sense is the section of the pipe outlet from the underground sewer to the house, even if it is heated. All the same, the ground near the foundation is often cold, and it is in this area that problems most often arise.

If you don't want to freeze your plumbing, heat your pipes. To do this, use a heating cable or heating plates - depending on the diameter of the pipes and the required heating power. Cables can be laid lengthwise or wound in a spiral.

Way of fixing the heating cable to the water pipe (the cable must not lie on the ground)

The heating cable is good for everyone, but it's not uncommon for us to have power outages for several days. What will happen to the pipeline then? Water will freeze and can burst pipes. And repair work in the midst of winter is not the most pleasant experience. Therefore, several methods are combined - and the heating cable is laid, and insulation is placed on it. This method is also optimal from the point of view of minimizing costs: under thermal insulation, the heating cable will consume a minimum of electricity.

Another way to attach the heating cable. To make electricity bills smaller, you also need to install a heat-insulating shell on top or fix rolled thermal insulation

Laying a winter water supply in the country can be done using this type of thermal insulation, as in the video (or you can take the idea into service and do something similar with your own hands).

Insulation of pipelines according to SNiP

When performing work on equipment and installation of pipelines, it is necessary to comply with the norms of SNiP.

What is SNiP? These are building norms and rules for the organization of construction production, for compliance with standards, specifications and regulatory departmental acts.

Basic norms and rules for thermal insulation

Heat networks are one of the main elements of district heating.It is necessary to strictly adhere to the norms and rules when drawing up a project for the thermal insulation of pipelines.

Subject to SNiP, thermal insulation of pipelines will be carried out qualitatively without violating standards.

Thermal insulation of pipelines SNiP is provided for linear sections of pipelines, heating networks, compensators and pipe supports.

Insulation of pipelines in residential buildings, industrial buildings requires strict compliance with design standards and a fire safety system.

The quality of materials must comply with SNiP, thermal insulation of pipelines must be aimed at reducing heat loss.

The main tasks of thermal insulation, features of the choice of materials

The main purpose of thermal insulation is to reduce heat loss in heating systems or pipelines with hot water supply. The main function of the insulation is to prevent condensation.

Condensation can form both on the surface of the pipe and in the insulating layer.

In addition, according to safety standards, the insulation of pipelines must provide a certain temperature on the surface of the insulation, and in case of stagnant water, protect it from freezing and icing in the winter.

Insulation of pipelines also increases the life of pipes.

According to the norms of SNiP, thermal insulation of pipelines is used both for centralized heating and reduces heat losses from in-house heating networks. What to consider when choosing thermal insulation:

• Pipe diameter. It depends on what type of insulator will be used. Pipes can be cylindrical, semi-cylinders or soft mats in rolls. Insulation of pipes of small diameter is mainly carried out using cylinders and half-cylinders.
• Heat carrier temperature.
• The conditions under which the pipes will be operated.

Types of heaters

Consider the most popular and frequently used materials for thermal insulation:

1. Fiberglass. Glass fiber materials are often used for above ground pipelines because they have a long service life. Fiberglass has a low application temperature and is characterized by low density. High-quality fiberglass has high vibration, chemical and biological resistance.
2. Mineral wool. Thermal insulation of pipelines with mineral wool is a very effective heat insulator. This insulating material will be used in different conditions. Unlike fiberglass, which has a low application temperature (up to 180ºC), mineral wool can withstand temperatures up to 650ºC. At the same time, its heat-insulating and mechanical properties are preserved. Mineral wool does not lose its shape, has a high resistance to chemical attack, acid. This material is non-toxic and has a low degree of moisture absorption.

In turn, mineral wool comes in two forms: stone and glass.

Insulation of pipelines with mineral wool is mainly used in residential buildings, public and domestic premises, as well as to protect surfaces that are heated.

1. Polyurethane foam has a wide range of applications, but is a rather expensive material. According to the norms of SNiP, thermal insulation of pipelines is environmentally friendly and does not affect human health. Polyurethane foam is resistant to external factors, non-toxic and quite durable.
2. Styrofoam.In some areas of industry, foam is an indispensable material, as it has low thermal conductivity and moisture absorption and a long service life. Expanded polystyrene is difficult to ignite, and is an excellent sound insulator.
3. In addition to the above materials, the insulation of pipelines can also be carried out using other less well-known, but no less practical heaters, such as foam glass and penoizol. These materials are strong, safe and are close relatives of Styrofoam.

Corrosion protection and high thermal insulation of pipes can also be provided by heat-insulating paint.

This is a relatively new material, the main advantage of which is that it penetrates into hard-to-reach places and is able to withstand high temperature differences.

Thermal insulation of the pipeline by creating high pressure in it

One of the options to insulate water supply pipes in a country house or in a private house is to create and maintain high pressure in them. The effectiveness of this method is due to the quality of water, being under high pressure, not to freeze.

Creating high pressure in the pipeline:

• A small receiver crashes into the water supply, with the help of which a pressure of 3-5 atmospheres will be created.
• When applying this method, submersible pumps are used, capable of pumping pressure of 5-7 atmospheres. Further, after this pump:
• a check valve is being installed;
• the valve in front of the receiver closes;
• the pump turns on.

The created pressure must be maintained in the water supply system during the period of time when it is not being used. When the pipeline needs to be brought back into operation, air is simply bled from the pipes.

How to find out the temperature of the coolant in the batteries

When there are doubts about the quality of the heating services provided, and the inhabitants of the apartment simply begin to freeze, measures should be taken to establish the cause. To do this, measure the temperature:

• air in the room;
• pipes;
• batteries;
• coolant - water in the heating system.

The data obtained will help to understand whether the room is really unreasonably cold or whether it is just a subjective feeling.

It must be taken into account that independent measurements of heating indicators are not direct evidence of a violation of the norms. However, they can serve as the basis for filing a complaint and inviting representatives of the service organization for control measurements.

We determine the temperature of the water in the central system

It should be noted that it is not so easy to reliably measure the temperature of the coolant in the central heating system. The most accurate indicator is only the air temperature in the room. However, you can do the following:

1. Open the tap, if it is installed on the radiator in the apartment.
2. Substitute a container under it, after placing a thermometer there.
3. Collect water.
4. Wait for the final reading of the thermometer.

This indicator must comply with the described standards, but upward deviation from them is also allowed. Maximum temperature deviation - up to 4 °C.

In addition, if air is found in the heating system of the apartment, you should contact the service organization.

We determine the indicators of hot water

There is another way to establish the truth, related to the fact that the temperature of the heating batteries in the apartment and the indicators of hot water supply are directly dependent. Therefore, it is advisable to measure the degree of water like this:

1. Open hot faucet.
2. Wait 3 minutes for the water to heat up to the maximum value.
3. Take a container and substitute it under the stream without closing the tap.
4. Immerse the thermometer in the center of the container.
5. Wait for final instrument readings.

If the device shows a number from 60 to 75 ° C, everything is normal with the coolant. If the temperature data is lower, it is possible that the water in the heating system is not heated enough.

The need to insulate water pipes

In winter, the soil at a distance of two meters from the surface can freeze up to -20 oC. This can adversely affect the functioning of the water supply. If its insulation is not enough, or it is completely absent, then the liquid inside will simply freeze. And the residents of the house will be left without water for a long time.

Waiting for it to thaw is not an option, because it is required constantly. You can try to warm the pipeline in various ways. But this approach is a partial solution to the problem. It is best to eliminate it in advance. To do this, it is necessary to place the pipeline under the level of soil freezing, and also install additional insulation for it.
