Copper pipe water. Corrosion resistance, if the connection time with ordinary pipe fittings is long, there will be leakage problems, if the welding process will be much safer. Stainless steel water pipe. With excellent corrosion resistance, hygiene, no rust, no scale, no dialysis release foreign matter, good self-cleaning, long service life, environmental protection, can be recycled 100%, will not cause secondary pollution to water quality, is one of the best pipeline conveying materials, the future to replace other materials of the pipeline probability is very large.
Composite water pipe: aluminum plastic water pipe. Once more popular, convenient construction, has good thermal insulation performance, the internal and external walls are not easy to corrosion, but should not be buried in the ground, the card joint is easy to leak. Copper plastic water pipe. Similar to the aluminum-plastic pipe, it is generally about 3 meters long, but there are more joints and it is easy to form patina. Steel plastic water pipe. Steel-plastic pipe is the upgrade of traditional galvanized pipe products, health, non-toxic, non-fouling, corrosion resistance, smooth pipe wall, long service life.
Plastic water pipe: UPVC water pipe: the interface is generally glued, and the freezing resistance and heat resistance are not good, so the hot and cold water pipes are rarely used, PVC pipe is suitable for wire pipes and sewage pipes. PPR water pipe. At present, the relatively perfect water pipe, non-toxic, corrosion resistance, hot melt seamless connection, can be used for hot and cold water pipes, can also be buried, but the installation is difficult and easy to leak.
