What is the difference between PE water supply pipe and PE drain pipe


Release time:

Oct 14,2021

The difference is in the materials used. PE water supply pipes are produced in full accordance with national quality standards, and the selected raw materials guarantee new materials (high-density polyethylene raw materials). Because PE water supply pipes are used to transport drinking water, it is essential to ensure that the pipes produced have sanitary permits. This is a basic point. The PE drainage pipe is used to transport sewage, so in the case of meeting the construction requirements, the material can be mixed with recycled materials.

pe water supply pipe andPE drain pipeCollectively referred to as PE pipe, so what is the difference between them?

The difference is in the materials used. PE water supply pipes are produced in full accordance with national quality standards, and the selected raw materials guarantee new materials (high-density polyethylene raw materials). Because PE water supply pipes are used to transport drinking water, it is essential to ensure that the pipes produced have sanitary permits. This is a basic point. The PE drainage pipe is used to transport sewage, so in the case of meeting the construction requirements, the material can be mixed with recycled materials.

PE给水管和PE排水管有什么区别

pe water supply pipe andPE drain pipeThe pressure is usually divided into 5 levels: 0.6 MPa, 0.8 MPa, 1.0 MPa, 1.25 MPa, 1.6 MPa, usually called 6kg, 8kg, 10kg, 12.5kg and 16kg. The higher the kilogram pressure, the thicker the pipe wall. The wall thickness of PE water supply pipe is required to be a positive tolerance, and PE drainage pipe is allowed to be a negative tolerance within the specified range. PE water supply pipe is a new material, and PE drainage pipe will be mixed with recycled materials, so the price difference between the two is relatively large. After all, the price is worth it. If quality is required, a reliable manufacturer should be selected.

The temperature that the two can withstand is 70°C, but the temperature is different. This PE can reach minus 30 ℃, but PPR can only reach minus 10 ℃. When you see here, you should also understand that this PE is more cold-resistant. For some cold areas, the water temperature in the water pipe is very low in winter. It is recommended to use PE more often, which is not easy to freeze.

pe drain pipeThe flexibility is good, such as easy to bend, which is both an advantage and a disadvantage, that is, it may be easily deformed in use, originally a straight line, but it may become a little bent in use. Therefore, in some places, PE is more used for cold water because of its good cold resistance, while PPR is more used for hot water. However, when used for heating, it may heat up rapidly, and when used alone, it may also affect the insulation effect.
