PPR is referred to in English polypropylene random copolymer (Polypropylene-Random). Commonly known as the three types of polypropylene. PPR pipe is galvanized pipe, UPVC water supply pipe, aluminum pipe, PE pipe, PE-X pipe, PE-RT pipe replacement products. The strength of polypropylene random copolymer technology, good temperature resistance guaranteed to become the main force of the pipe material, it has the following advantages: 1, the health and environmental protection. Polypropylene is environmentally friendly materials, can be used as drinking water delivery. 2, joint with hot melt connection, become one hundred percent no leakage other material wire port connection, its impermeable inferior, but also to avoid the glue-toxic. 3, high temperature, pressure resistance, transport small resistance. Cheap moderate. 5, long life, the national the standard GB/T18742 production and use can be used for 50 years. PPR is RIZATION polyethylene short, thermal welding, special welding and cutting tools, high reliability. The price is also very economical. Insulation performance is also very good, very smooth wall! General prices in the $ 4-8 per meter (4 in charge). Does not include the internal and external wire connector. PPR pipe formally called random copolymer polypropylene tubes, is a home improvement project using a water supply pipeline. > Why is not the same as PPR pipes color? · This will be due to the raw material the PPR particles of different. So water pipes on Haipiersa is white and white butterfly is gray, not on behalf of said product quality and grade. > PR plumbing is how to distinguish sub cold water pipes and hot water pipes? · PPR pipe is divided into the cold water pipe with hot water pipe, the difference is that the blue marking line on the cold water pipe, hot water pipe is a red line> the PR water pipe connection technology What are the characteristics? · PPR pipe interface with hot-melt technology between the tube fully integrated into together, so once installed to suppress the test is passed, will not water leakage, high reliability. > PR plumbing What are the disadvantages? · PPR water pipe defects: high temperature and pressure resistance somewhat less more long-term working temperature can not be more than 70 ° C; each piece of limited length, and can not be bent construction, pipe laying long distance or corner construction is necessary to use a large number of joints; pipe cheap accessories price is relatively high. However, from the terms of overall performance, PPR pipe is the high cost of the pipe, and so become the material of choice for home improvement plumbing renovation.
