1. Pression
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.
Les tuyaux de drainage en polyéthylène sont généralement utilisés pour évacuer les eaux usées et s'écouler de haut en bas, de sorte que les tuyaux de drainage en polyéthylène n'ont généralement pas besoin de prendre en compte le niveau de pression.
2. Prix
Étant donné que le tuyau d'alimentation en eau en PE est fait de nouveau HDPE, son coût sera supérieur à celui du tuyau de drainage en PE.
3. Matériaux
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.
