Polypropylene taps and fittings (PPR, PPR)

Pipeline systems are inextricably linked with the level of development of any civilization. Even some 100 years ago, a polypropylene fitting and pipes that can withstand pressure of 25 atm and temperatures up to 100 degrees would have been just fantastic. But with the development of the chemical industry, materials have appeared that can replace metal as a material for the production of pipelines, both in terms of price and consumer qualities. Fittings and pipelines made of PPR are lightweight (8-9 times lighter than metal ones), are not subject to corrosion, practically do not clog due to the absence of internal friction, have dielectric properties and do not transmit sounds. Polypropylene fittings and pipes do not react with alkalis and acids and are not affected by aggressive liquids, which expands the possibility of their use in the food and chemical industries. The production of polypropylene pipes and fittings is possible in various colors, so the pipes do not require additional painting and maintenance in the future. For the installation of the pipeline, a soldering iron for PPR fittings with a temperature controller is used, since the optimum welding temperature should not exceed 260 degrees Celsius. The soldering iron, during the time specified in the manual for a given diameter, heats and melts the edge of the pipe at the junction and the inlet of the fitting, after which both parts immediately connect and cool down, forming a single non-separable connection. The use of brass inserts with external and internal threads makes it possible to connect PPR fittings with steel pipelines and devices, as well as increase the reliability of connections and guarantee their tightness.
