Pipe insulation made of expanded polyethylene

Pipe insulation made of foamed polyethylene is a material that has high flexibility, as well as resistance to various kinds of mechanical damage. This protection is not terrible effects of gypsum, gasoline, oils, and also lime. The surface is able to undergo the temperature of the coolant, which can reach 90 degrees. The insulation has the form of tubes, which are installed on the main pipes of the system by the method of simple tension. If the pipe insulation is mounted on an already installed system, it will be necessary to cut through a special longitudinal line. The obtained seams should be glued with the help of a formulation designed for this purpose. Thanks to the presence of a longitudinal cut of the tube, it is possible to cut not only smoothly, but also quite simply, providing a fast and fast installation. Excellent characteristics of the described thermal insulation can save on heating, as well as reduce the final weight of structures, reducing the consumption of building materials.

Key Features

Pipe insulation is produced by extruding polyethylene granules. As a result, it is possible to obtain a structure that possesses small closed pores. The material contains a significant amount of air, which provides heat insulation qualities. Products have high elasticity and flexibility. On sale, you can find many sizes, while the length of the pipes is two meters. The color of the tubes is gray, and along the entire length there is a mounting cut. Pipe insulation of the type described can be used for pipelines made of steel and copper.

Appointment

Products are used to protect cold pipelines that are located inside the structure. As a function of insulation in this case, the prevention of condensate formation. It should be noted that the latter phenomena can cause a shortening of the life of the pipeline. The insulation is also used in freezing plants when it is necessary to keep the temperature of the carrier low. Quite often, these products can also be found in the arrangement of hot water systems, which are located inside the buildings. In this case, the preservation of the initial temperature also serves as the problem. If insulation is used outside of buildings, then it is able to prevent freezing. Among other things, this material can protect a person from the possibility of getting dangerous burns. Inside the room, operation is allowed without additional recommendations, while outside it is necessary to install insulation, protecting it from direct sunlight. In this case, the material can undergo an effect from -40 to +70 degrees. Humidity is allowed up to 100%. The temperature of the coolant in the pipeline can vary from -40 to +100 degrees.

Advantages of use

If "Thermaflex" pipe insulation is used, then you can be sure that the material is absolutely hygienic and safe for human health and ecology. It is completely inert, does not form dust and has no foreign smell. It can be used in objects of different purposes, up to medical institutions and food industry buildings. Insulation of this type is completely impermeable to steam and water. It prevents the appearance of fungus and resists rotting. In addition, it is not necessary to protect the insulation, among other things, it is able to prevent corrosion, as well as the impact on the pipes of concrete, cement, lime and gypsum mixtures. The "Thermaflex" pipe insulation reduces acoustic noise and reduces the structural sounds that can arise during operation in the system. Installing products is easy enough, in work they are economical in terms of labor, which is very much in the spirit of the modern consumer. Such insulation is longevity, its life is much longer than that of the pipeline itself.

Features of the installation

K-Flex pipe insulation should be installed after the surface has been thoroughly cleaned of grease and rust contamination. Work should be performed only on non-functioning equipment. Ensure de-energization is necessary 24 hours before the start of installation work. If necessary, you can cut by using a sharp knife. When laying it is important to ensure absolute tightness. To do this, use a special adhesive "Energoflex".

Installation on an uninstalled system

If you use the pipe insulation "Energoflex", which is installed on an unmounted system, it is necessary to put the tubes on the pipes. When welding, it is necessary to protect the material from the melts. After the seams have cooled, they should be cleaned and the insulating material carried on them . At the final stage, the insulation is glued together at the ends between them. Jointing of seams can be made with the help of construction staples. In order to provide additional sealing of joints, it is possible to use reinforced tape. If the pipeline will be in the ground during operation, it should be protected by a casing, which will allow to exclude damages received by elements of soil.

Advantages and disadvantages

Pipe insulation made of polyethylene has an insignificant coefficient of thermal conductivity, this indicates that the material can effectively provide its material with insignificant thickness. The insulator described has a rather impressive mechanical strength to tensile forces. That is why, after deformation, the material sufficiently well restores its original shape. Use during installation does not need additional tools. One of the important advantages of this heat insulator is the low cost, which is almost half as much as that of analog materials. This makes foamed polyethylene cost-effective for working on large pipelines. However, one can only single out a drawback. It is expressed in flammability. This causes the inability to use this insulation at sites to which high fire safety requirements are imposed.

Specifications

Pipe insulation K-Flex ST has a density that can vary from 25 to 40 kg per cubic meter. Among other things, you can distinguish an excellent elasticity, which is maintained to -80 degrees. This allows you to use this material on any pipes, whatever form they have. The highest tensile load that this insulation can withstand is 0.3 MPa, while the insulation has a dynamic modulus of elasticity, which is equivalent to 0.77 MPa. As for the compression ratio, which is maintained under external load, it is equal to 0.2. If you purchase a pipe insulation from Rockwool, you should pay attention to the coefficient of thermal conductivity, as a rule, this figure varies within the range of 0.035 W / μ. As for the coefficient of vapor permeability, it is 0.001 mg / MhPa. It is according to this indicator that the described insulation can be classified as a class of materials that are completely vapor-proof. Pipe insulation from foamed polyethylene absorbs water in an amount of 1.5% of its volume after being in water for a day. This indicator increases by a tenth of the percentage with an increase in the time of exposure to water. Thus, if you put a heater for 28 days in water, it will absorb 1.9% of its weight.

additional characteristics

The thickness of the material can vary from 6 to 20 millimeters. The intermediate values are 9 and 13 millimeters. On sale you can find a great variety of standards for the diameter of the sleeve, this parameter ranges from 12 to 200 millimeters. In the field of industry, the internal diameter is most often used, equal to 100 and 150 millimeters. In the production process, in addition to the foamed reagent, various special additives are added to the ingredients, which are designed to give the final product the required characteristics, namely, elasticity and refractoriness. As for the latter, the heater is classed as moderately combustible.

Conclusion

If there is a need to prevent condensation or protect the pipes from corrosion, the pipe insulation described above should be used. By purchasing this material, you can not be afraid for the fact that it will be able to do harm. This is due to the fact that a heater of this kind is made from environmentally friendly ingredients. For these reasons, in modern industry and in the arrangement of private pipelines, a heater of the type described above is used, which is inexpensive and has truly outstanding qualities.
