As a new type of plumbing material, ppr is chosen by the majority of families

As a new type of water pipe material, it can be used as a cold pipe or a hot water pipe. Because of its non-toxicity, light weight, pressure resistance, and corrosion resistance, it is becoming a popular material. It is also suitable for hot water pipes and even pure drinking water pipes. The interface of the PPR pipe adopts hot-melt technology, and the pipes are completely fused together. Therefore, once the installation and compression test passes, it will not have a long aging and water leakage like the aluminum-plastic pipe, and the PPR pipe will not scale. The main drawbacks of PPR water pipes are: high temperature resistance, poor pressure resistance, long-term working temperature can not exceed 70 ℃; large linear expansion coefficient, the pipe is easy to deform after hot water, which affects the appearance; each length of straight pipe is 4 meters / Root, the coil is 100 meters---300 meters. And it cannot be constructed at a small angle. If the pipeline is laid for a long distance or there are many corners (small angles), a large number of joints will be used in the construction; the pipes are cheap but the price of the accessories is relatively high.
