1. Ciśnienie
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.
Rury drenażowe z polietylenu są zwykle używane do odprowadzania ścieków i przepływu od góry do dołu, więc rury drenażowe z polietylenu na ogół nie muszą uwzględniać klasy ciśnienia.
2. Cena
Ponieważ rura wodociągowa PE wykonana jest z nowego HDPE, jej koszt będzie wyższy niż koszt rury drenażowej PE.
3. Materiały
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.
