1. Pritisk
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.
Polietilenske drenažne cevi se običajno uporabljajo za odvajanje odplak in pretok od zgoraj navzdol, zato polietilenske drenažne cevi na splošno ni treba upoštevati stopnje tlaka.
2. Cena
Ker je PE dovodna cev izdelana iz novega HDPE, bo njen strošek višji kot pri PE drenažni cevi.
3. Materiali
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.
