1. Tekanan
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.
Paip saliran polietilena biasanya digunakan untuk membuang kumbahan dan mengalir dari atas ke bawah, jadi paip saliran polietilena secara amnya tidak perlu mempertimbangkan gred tekanan.
2. Harga
Oleh kerana paip bekalan air PE diperbuat daripada HDPE baharu, kosnya akan lebih tinggi daripada paip saliran PE.
3. Bahan
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.
