1. Þrýstingur
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.
Pólýetýlen frárennslisrör eru almennt notuð til að losa skólp og renna frá toppi til botns, þannig að pólýetýlen frárennslisrör þurfa almennt ekki að taka tillit til þrýstingsstigsins.
2. Verð
Þar sem PE vatnsveiturörið er úr nýju HDPE verður kostnaður þess hærri en PE frárennslisrör.
3. Efni
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.
