PE water supply pipes are produced in strict accordance with national hygiene standards. The raw materials are all high-density polyethylene, without any recycled materials and other additives. In terms of pressure, PE water supply pipes are used to transport tap water, which generally needs to be pumped from the ground to the ground and residents' homes. Since the PE water supply pipe needs to bear the pumping pressure, the water supply pipe is generally divided into five levels according to the pressure, namely 0.6 MPa, 0.8 MPa, 1.0 MPa, 1.25 MPa, and they bear 6 kg pressure, 8 kg pressure, 10 kg pressure , 12.5kg pressure and 16KG pressure. The higher the pumping pressure, the higher the pressure level requirements for the PE water supply pipe. Polyethylene drainage pipes are generally used to discharge sewage and flow from top to bottom, so polyethylene drainage pipes generally do not need to consider the pressure level. In terms of price, the cost of PE water supply pipe is higher than that of PE drainage pipe. In terms of materials, PE water supply pipes need to deliver tap water for people's daily life, so PE water supply pipes must meet national health standards, and PE water supply pipes must also use high-density polyethylene that meets national standards.
