Plastic pipes are replaced with metal ones to improve the thermal insulation and performance of the systems. Depending on the type and scope of purpose, they are made from polypropylene, polyethylene, polyvinyl chloride or metal-plastic. According to the site http://www.plastprofil.ru most often plastic pipes are used in the installation of heating, sewerage and water supply systems.
Besides the appearance, plastic pipes have several advantages:
- plasticity of the material - freezing of the liquid inside the pipes does not provoke a violation of the integrity of the elements of the complete system. The constant differential pressure also causes serious damage. Freezing or critical pressure rise results in pipe deformation and sagging;
- durability - about 50 years of operation;
- low heat transfer - especially important in heating systems;
- ease of installation;
- relatively light weight;
- low cost;
- corrosion resistance;
- environmental friendliness of the material.
The advantages of plastic pipes are to a small extent offset by their average resistance to damage. The use of polymer parts in heating systems is also limited, since plastic has a relatively low melting point. Due to the limitation of 95 ° C, pipes are not used in fire protection systems.
Installation of plastic pipes is carried out using heating devices, which melt the top layer of material for reliable fastening of the elements of the general system by means of fittings. Polymer pipes allow you to create complex outdoor and hidden systems.
