The varieties and applications of plastic pipes have developed rapidly in the past few years. China's plastic pipes have developed into a building material industry with complete varieties and large production capacity. The main types of plastic pipes are UPVC pipe, CPVC pipe, PE pipe, PAP pipe, PE-X pipe, PP-B pipe, PP-R pipe, PB pipe, ABS pipe, steel-plastic composite pipe, glass fiber reinforced pipe and so on.

1. PVC pipes. PVC pipes have poor antifreeze and heat resistance properties. PVC pipes are suitable for use as electrical and sewage pipes, and they are filled with phthalein.
2. PE pipe. It can be used for both hot and cold water pipes because it is non-toxic, lightweight, has good compressive and corrosion resistance properties, and is worth promoting as a material. The PE pipe interface adopts hot melt technology, and the pipes are well combined. After installation, perform a pressure test. If there are no problems, it will not age or leak due to prolonged use, and the PE pipe will not scale.
3. Aluminum plastic composite pipe. Its material is very light, very durable, easy to construct, and its bending performance is more suitable for home decoration. The disadvantage is that if it is used as a hot water pipe, it may cause long-term thermal expansion and contraction, which may result in misalignment of the sleeve type connection and leakage.
