1. Pritisak
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 cijevi općenito se koriste za ispuštanje kanalizacije i protok od vrha do dna, tako da polietilenske drenažne cijevi općenito ne moraju uzeti u obzir stupanj tlaka.
2. Cijena
Budući da je PE dovodna cijev izrađena od novog HDPE-a, njezina će cijena biti veća od PE drenažne cijevi.
3. Materijali
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.
