1, Work pressure
PE water supply pipes are used to transport tap water, usually requiring pumps to pump water from underground to the ground and transmit it to households. Due to the fact that PE water supply pipes need to bear the working pressure of the pump during pumping, they are usually divided into five levels according to the size of the pressure, namely 0.6Mpa, 0.8Mpa, 1.0Mpa, 1.25Mpa, 1.6Mpa. They each bear 6 kilograms of working pressure, 8 kilograms of working pressure, and 10 kilograms of working pressure 12.5 kilograms of working pressure and 16 kilograms of working pressure. The higher the pump's pumping pressure, the higher the required working pressure level of the PE water supply pipe.
PE drainage pipes usually discharge sewage from high altitude to low altitude, so PE drainage pipes usually do not need to consider the working pressure level.
2, Price
Due to the use of newly upgraded high-density polyethylene raw materials in PE water supply pipes, the relative cost will be higher than that of PE drainage pipes.
3, Raw materials
PE water supply pipes need to transport tap water for everyone's daily drinking water. Therefore, PE water supply pipes must meet China's quality standards, and the raw materials of PE water supply pipes must also be high-density polyethylene that meets national industry standards.
4, Hygienic standards
PE water supply pipes are strictly produced in accordance with national hygiene standards, with all raw materials made of high-density polyethylene and never mixed with any recycled materials or other additives.
When PE drainage pipes meet the applicable conditions and are allowed by the customer, they can be added with recycled materials for the customer to choose for themselves.
