1. Tlak
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.
Polyetylenové drenážní trubky se obecně používají k vypouštění odpadních vod a proudění shora dolů, takže polyetylenové drenážní trubky obecně nemusí brát v úvahu stupeň tlaku.
2. Cena
Protože PE vodovodní potrubí je vyrobeno z nového HDPE, jeho cena bude vyšší než cena PE drenážního potrubí.
3. Materiály
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.
