Reinforced special PP-R fusion pipe fittings 7

PPR pipe, officially known as random copolymer polypropylene pipe, is currently the most commonly used water supply pipeline in home decoration projects. The quality control issue of PPR pipe raw materials. PPR is a random copolymer polypropylene synthesized by the gas-phase method of (PP and PE), and its structural feature is that PE molecules are irregularly linked in PP molecules, with molecular weights ranging from 300000 to 800000. The pipes produced using PPR raw materials, also known as random copolymer polypropylene pipes, are plastic pipe products developed and applied in the late 1980s and early 1990s. It has occupied a place in the plastic pipe market with its excellent performance and wide range of applications, and is recognized as a green and environmentally friendly product. However, in recent years of market operation, the analysis of quality issues with PPR plastic pipes mentioned above has revealed many problems in the PPR pipe market, which have greatly hindered the healthy development of PPR pipes.

PPR pipe connection technology:

Generally, there will be no more water leakage and the reliability is extremely high. But this does not mean that PPR water pipes are defect free. Their high temperature resistance and pressure resistance are slightly inferior, and their long-term working temperature cannot exceed 70 ℃; Each section has a limited length and cannot be bent during construction. If the pipeline is laid for a long distance or at many corners, a large number of joints will be required during construction; The pipes are cheap, but the prices of accessories are relatively high. In terms of comprehensive performance, PPR pipe is a cost-effective pipe material, making it the preferred material for home water pipe renovation.
