Can pvc water pipes be used as tap water pipes?Can pvc water pipes be used as tap water pipes?
PVC water pipes can be used as tap water pipes. There are many types of PVC pipes, including PVC water supply pipes, PVC drainage pipes, and pipes for other purposes, such as wire bushings, and new material PVC-M pipes. Used as domestic water-the pvc pipe of the tap water must be a pvc water supply pipe, and cannot be replaced with pvc pipes for other purposes.
pvc water supply pipe
The requirements for pipes used in domestic water are higher than those for drain pipes. New PVC materials are required for the production of PVC water pipes, and they must be environmentally friendly. They must not release harmful substances to domestic water, and the pressure capacity must meet the requirements of domestic water pressure. As long as the health indicators, non-toxic and non-polluting and other testing indicators are qualified, there is no problem. As long as these standards are produced according to the corresponding process, pvc material water pipes are fully competent!
In fact, the advantages of PVC water supply pipes are also many fluid resistance:
The inner wall of the pipe is smooth, the roughness coefficient is only 0.009, and the fluid resistance is small, which effectively improves the hydraulic conditions of the pipe network and reduces the operating cost of the system.
Large mechanical strength: The pipe has good pressure resistance, impact resistance and tensile strength properties. Simple construction: the pipeline connection construction is quick and easy, and the construction cost is low.
Low cost: low price, convenient transportation and construction, and long service life, so the overall cost is low.
That is, due to the two characteristics of easy construction and low cost of PVC water supply pipes, many rural areas will choose PVC materials as tap water pipes.

However, the pipes for household use are generally ppr hot melt pipes. The pipes of this material are more expensive than PVC pipes. Of course, they are also more advantageous than PVC pipes. It has better impact resistance and long-term creep performance. The interface is connected by hot melt, as long as the process is operated, the possibility of water leakage in the later period is very small.
