The pipelines used for the construction of tap water pipes not only have the requirements of pressure and ring stiffness, but also the requirements of environmental protection level. In China, the most commonly used pipes for tap water are mainly PE pipes and PPR pipes. Among them, PE pipes only need to be used for municipal tap water. It is mainly used for indoor construction, while PPR pipes are mainly used indoors. The same is a plastic pipe, can the PVC pipe be used as a water pipe?
The main raw material of PVC pipe is polyvinyl chloride, and at the same time, there are various additives such as calcium carbonate powder, stabilizer, lubricant, titanium dioxide, whitening agent, etc. The chemical additive phthalein in PVC pipe can cause cancer, kidney damage, damage The human body function reconstruction system affects development, and its strength cannot meet the pressure requirements of water supply pipes, so conventional PVC pipes, such as PVC drainage pipes and PVC line pipes, cannot be used as water pipes.
PVC water supply pipes can meet the design requirements of water pressure, and are generally produced with new materials. The environmental protection performance is much higher than that of PVC drainage pipes. There have also been a small number of water pipes used as water pipes, but the connection of PVC pipes generally requires the use of chemical glue. For long-term use, there is still the risk of precipitation of toxic substances. If it is used as drinking water, there are certain hidden dangers. Therefore, it has generally been replaced by hot melt connected PPR pipes and PE pipes.
