Thermal insulation of pipes and the most popular types of heaters

Qualitative heat insulation of pipes - necessarycondition in order to prevent heat leakage, avoid condensation and freezing of the pipeline located outside the heated room.

Value of thermal insulation

The main purpose of insulation for pipes isreduction of heat loss. Correctly selected and installed with observance of technology, heat-insulating material can reduce heat losses by 25%. In addition, it also serves to solve many other problems.

Thermal insulation for water pipes helpsprotect them from freezing and gusts. In the climatic conditions of Russia this is especially important. Thermal insulation of pipes using reliable modern materials allows to ensure uninterrupted water supply at any time of the year.

Apply thermal insulation and forthe opposite goal - when it is required to avoid the heating of the working substance. Such properties of a heater are necessary in systems for transfer of liquid gases, in refrigerator installations and some other devices.

Basic requirements for thermal insulation

The effectiveness of the chosen insulation depends largely on its technical characteristics.

It should be designed directly for pipes. If the roll insulation is mounted without any problems, then the rigid material is selected in appropriate shapes and sizes, taking into account the diameter of the pipe.

Pay attention to the abilitymaterial to moisture absorption. It should be minimal, because the wetting insulation significantly reduces the protective function. In most cases, the insulation of pipes is carried out independently, without the involvement of specialists, so the preference should be given to materials that have a simpler mounting technology.

Essential factors in choosing a heater are its long service life, compliance with fire and sanitary standards, as well as the cost of the material.

Popular thermal insulation materials

  • Polyurethane foam.In domestic use it is the most convenient in use and effective insulation. Available in the form of half-cylinders (shell) of different diameters and thickness, which are attached to the pipe using clamps or mastic. The advantage of the shell is that it completely eliminates the formation of the effect of steam such heat insulation of the pipes. The price for 1 running meter of this heater is relatively low - from 100 to 250 rubles. As a covering for this material, foil, galvanized steel (for external laying), fiberglass, polyethylene (for laying in the ground) are used. The shell of polyurethane foam is able to withstand temperatures from -180 to +135 ° C. Use for coating and seamless method, when polyurethane is sprayed on the surface of the pipe, which provides maximum protection.
  • Mineral wool.Used as a heater for metal, plastic, as well as other types of pipes. This material is the most democratic at a price (6 sq. M. Will cost 450 rubles), so it is used rationally where large volumes are required: for the construction of heating mains, water supply lines, etc. The disadvantage is that the insulation of pipes with the help of Mineral wool requires additional protection against moisture.
  • Foamed thermal insulation.It is characterized by increased strength and is made of a foam that does not support combustion. The possibility of reusing this thermal insulation material allows to save time when creating temporary communications. This is one of the more economical and reliable heaters.

Other types of heaters

Today it is gaining popularity and moremodern thermal insulation for water supply pipes. The novelty can be attributed foil insulation, which has a heat-reflecting effect. It protects well against the penetration of water. Many industrial sites use thermo-lacquer, characterized by high thermal insulation ability with a minimum layer. Apply with a normal brush or roller. To cover large areas - using a sprayer. In addition to the main function of such insulation protects metal pipes from corrosion and gives them a more aesthetic appearance.

Foamed polyethylene also can be attributed to effective materials. Thermal insulation of pipes with its use helps to keep the temperature the same as at the outlet from the boiler.

Installation of heat-insulating materials

In order to insulate the pipeline with a roll,sheet or molded material, special equipment is not required. This can be done on their own, with a knife, an adhesive tape, a brush, a galvanized wire, and an anti-corrosion primer mixture.

The surface of the metal pipe is first neededcarefully clean the dirt and apply a primer layer on it. Then tightly wrap the pipe with reinforced tape, fixing the seams with a wire. Further heat insulation of heating pipes is carried out depending on the shape of the insulation. Fastening of casing materials is carried out due to special grooves. Cylindrical tubes are installed before the installation of the system, and on the already installed pipeline - after cutting and further sealing with special glue.

Warming of pipes in the ground

Paving communications in the land is compulsoryrequires insulation of pipes with thermal insulation materials. This is taken into account when calculating the width of the trench. At the bottom it is desirable to put a sand or claydite pillow. Pipes are wrapped with a heater, which is attached depending on its type by tape or wire.

heat insulation of sewer pipes
Often the insulation of sewer pipes running underground is performed by a combined method. Most materials are successfully combined, providing a good effect.
