Pipes for water plumbing construction. There are not only pressure and ring stiffness requirements, but also environmental protection ratings.

The chemical additive phthalein in PVC pipes can cause cancer and kidney damage. Damage to the functional reconstruction system of the human body affects development. Its strength cannot meet the pressure requirements of the water supply pipe. Therefore, conventional PVC pipes, such as PVC drainage pipes, PVC line pipes, etc., cannot be used as water supply pipes.
The PVC water supply pipe can meet the design requirements of water pressure. Generally, new materials are used for production. Environmental performance is much higher than that of PVC drainage pipes. There are also a small number of water pipes used as water pipes. However, the connection of PVC pipes generally requires the use of chemical glue. Long-term use, there is still the risk of toxic substances precipitation. If it is used as drinking water, there are certain hidden dangers. Therefore, it has been generally replaced by PPR pipes and PE pipes that are hot-melt connected.
