1. Pressure
PE water supply pipe is used to deliver tap water. Generally, it needs to pump water from underground to the ground and residents' homes. Because PE water supply pipes need to bear pumping pressure, water supply pipes are generally divided into five levels according to pressure, namely 0.6 MPa, 0.8 MPa, 1.0 MPa and 1.25 MPa. They bear 6 kg pressure, 8 kg pressure, 10 kg pressure, 12.5 kg pressure and 16 kg pressure. The higher the pumping pressure, the higher the pressure level of 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 grade.
2. Price
Since the PE water supply pipe is made of new HDPE, its cost will be higher than that of PE drainage pipe.
3. Materials
PE water supply pipe needs to deliver tap water for people's daily life, so PE water supply pipe must meet the national health standards, and PE water supply pipe must also adopt high-density polyethylene that meets the national standards.
