PVC pressure pipes for water are light in weight and relatively low in sales cost. They have a bell shaped cover with a sealed environment, which can be tightly connected without using additional seals. No welding machine or complicated tools are required for installation. Because of its simplicity, installation can be done manually.

Since the pressure pipeline is not easy to deteriorate and corrode, the inlet water is clean. PVC products are characterized by reduced flammability. The inner surface of PVC pipes is always free and clean, because salt will not accumulate and deposit on the pipe wall. This characteristic enhances the service life of the product.
