To date, a heating system from polypropylene pipes has become very widespread. And this is due to the fact that modern plumbing products have a number of capabilities and advantages that their predecessors did not have (polyvinyl chloride pipes and fittings made of polyethylene).
Benefits
Polypropylene industrial products are very durable. If you choose the right type correctly, they can last 50 years or more. Polypropylene pipes, due to the unique composition and manufacturing technology, do not require additional painting and insulation, do not collect condensate on the surface.
Heat savings using these products are 20%. Pipes do not rust, lime deposits and deposits do not form inside them, in addition, the inner walls are perfectly smooth, which eliminates friction and resistance, so that water flows freely through the pipe. They are not a conductor of electric current. In addition, the heating system made of polypropylene pipes is able to withstand a record temperature mark of 95 ° C.
Products are convenient in transportation and installation, since they are much lighter than metal. They are easily cut with special scissors. Installation of a heating system with polypropylene pipes takes little time. A special soldering tool is required to connect the pipes and fittings together. Moreover, the ends of the products do not need to be pre-cleaned. Due to the strong connection, the heating system from polypropylene pipes is considered to be reliable.
Mounting
When mounting products, it is impossible to subject them to distortions or bending, since polypropylene is a rigid material, which means that all turns and other actions must be carried out using polypropylene fittings. Installation work is best entrusted to professionals, otherwise there is a risk of getting a poor-quality heating system. If necessary, the polypropylene pipe can be slightly bent, heating it in the right place with a building hair dryer. However, in the case of strong pressure on the material, the product may undergo deformation or break.
Currently produce pipes up to 4 meters long. Three types of products are made, each of which is intended for a specific application (PN10, PN20, PN25). The heating system from polypropylene pipes is mounted, as a rule, from PN25. This species differs from others in that it is internally reinforced with aluminum foil, and therefore not plastic. Due to the reinforcement, pipes of the third group can be used at pressures up to 8 atmospheres and water temperatures up to 70 ° C, while the service life is 50 years. But if the pressure characteristics and water temperature increase, the service life of the pipes will decrease.
Conclusion
In any hardware store, you can purchase polypropylene pipes for heating. Their price is relatively low, which makes them affordable. The cost depends on the diameter (from 25 to 125 mm) and varies from about 40 to 1500 or more rubles per meter. Most have already seen the high quality of the material and the democratic prices.
