Household water pipes are generally divided into water supply pipes (inlet pipes) and drain pipes (down water pipes). There is nothing to say about the sewer pipes, usually PVC pipes. As long as the pipes are durable, pay attention to the slope of the drainage and the protection of the water pipes. The inlet pipe is relatively more complicated, and there are a lot of attention to materials and construction. Moreover, most of the waterways are concealed projects. If they are leaked, it will cause a lot of trouble.
Gradually, PPR pipes have entered everyone's field of vision.
①Environmental protection: The main material is random copolymer polypropylene, which is non-toxic and tasteless, and will not pollute water sources. Bacteria will grow only when the water is static for a long time, but who will not use water for a long time?
②High temperature resistance: The temperature resistance range is about -15°~95°. Although the maximum temperature is slightly lower than that of aluminum-plastic pipes, it is enough to meet household water temperature. Blue and red lines are generally used to mark cold water pipes and hot water pipes on water pipes. But now there is no strict distinction. Because the hot water pipe has a thicker wall and better quality than the cold water pipe, hot water pipes are generally used for cold water in renovation.
③Long service life: strong pressure resistance, the working pressure of the water pipe system can reach 2.0Mpa~2.5Mpa, and many brands promise that it can be used for 50 years.
④ Water-proof: PPR pipe connection uses hot-melt technology. As long as the water pipe is qualified, the hot-melt connection technology is reliable and can never leak.
