The difference between PE water supply pipes and PE drainage pipes
1. Pressure PE water supply pipes are used to deliver tap water, typically requiring water to be pumped from underground to the surface and into residential homes. Since PE water supply pipes must withstand pumping pressure, water supply pipes are generally classified into five pressure levels: 0.6 MPa, 0.8 MPa, 1.0 MPa, 1.25 MPa, and 1.6 MPa—corresponding to pressure ratings of 6 kg/cm², 8 kg/cm², 10 kg/cm², 12.5 kg/cm², and 16 kg/cm², respectively. The higher the pumping pressure, the higher the required pressure rating for the PE water supply pipe. Polyethylene drainage pipes are generally used to discharge wastewater and flow from top to bottom; therefore, polyethylene drainage pipes typically do not need to consider pressure ratings.
