Pipe insulation made of expanded polyethyleneis 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 make a cut along a special longitudinal line. The obtained seams should be glued using the formulation developed for these purposes. Thanks to the presence of a longitudinal cut of the tube, it is possible to cut not only smoothly, but also simply enough, providing 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.
Pipe insulation is produced by the methodextruding polyethylene granules. As a result, it is possible to obtain a structure that has small, closed pores. The material contains a significant amount of air, which provides thermal insulation qualities. Products have high elasticity and flexibility. On sale you can find many sizes, while the length of the tubes 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.
Products are used to protect coldpipelines 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 reduction in the life cycle of the pipeline. The insulation is also used in freezing plants, when it is necessary to keep the carrier temperature extremely low. Quite often, these products can be found even 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, it is able to prevent freezing. Among other things, this material can protect a person from the possibility of obtaining 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.
If pipe insulation is used"Termafleks", 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 decay. 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 simple 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.
K-Flex pipe insulation must be installedafter the surface is well cleaned of contamination, represented by grease and rust. 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".
If you use 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 insulation 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 is located in the ground during operation, it should be protected with a casing that will allow to exclude damages received by soil elements.
Pipe insulation from polyethylene hasan insignificant coefficient of thermal conductivity, this indicates that the material can effectively provide its material with an insignificant thickness. The insulator described has a rather impressive mechanical strength to tensile forces, which is why, after deformation, the material sufficiently well restores its original shape. Use during installation does not need additional tools. As one of the important advantages of this heat insulator is low cost, which is almost half as much compared to 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.
Pipe insulation K-Flex ST has a density,which 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 at an external load, it is equal to 0.2. If you purchase a Rockwool pipe insulation, 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 / MpPa. It is according to this indicator that the described insulation can be attributed to 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.
The thickness of the material can vary from 6 to 20millimeters. 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 classified as a moderately flammable class.
If there is a need to preventcondensation or protect the pipes from corrosion, the pipe insulation described above should be used. By purchasing this material, you can not be afraid 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.
