What is the Performance of HDPE Pipe Water Supply and Improvement of Roughness?

Pulished on Apr. 15, 2020

As an HDPE Pipe Supplier, share with you. With the continuous improvement of people's living standards, people pay more and more attention to health, so changing the water quality of water supply pipes is also essential. The polyethylene water supply pipe is made of stable polyethylene, which has the characteristics of high temperature resistance and deformation resistance.



The length of the HDPE Pipe is about 6 meters, which is convenient for transportation, while saving freight and reducing transportation costs. At the same time, the pe water pipe is divided into two types: straight pipe and coil pipe. It is used in various water supply projects. It has good quality and low price, so people can use it more confidently and comfortably.

The PE water supply pipe also has excellent properties such as cold resistance, heat resistance, corrosion resistance, wear resistance, and even service life. The PE water supply pipe is a green and non-polluting pipe, and the material can be recycled. Since the pipe is not rusty, it is not only conducive to environmental protection, but also beneficial to the replacement of ordinary hot water supply pipes.

When using PE water supply pipes to find the back will be a rough phenomenon, in fact, this phenomenon may be a big reason. If a new material, they can be excluded from the supply pipe which has a rough surface, but if the roughness that appears in the thin layer on the surface is replaced, it can be formed in the mold part.

Because the raw materials are heated in the machine head or barrel for a long time, the machine head and barrel are not clean or the processing temperature is too high or the screw is damaged and easy to age. Large pits or holes are easily formed during the extrusion process. If this happens, the machine should be turned off for about 1.5 hours and the broken material added. If the machine is stopped for 4 hours, the temperature should quickly drop to 150 to 200 degrees Celsius. To limit the decomposition of raw materials.

When the raw material is wet, some small bubbles on the surface of the PE water pipe will also form pits after molding. This pockmark has a small tail, which is formed by extending in the opposite direction of the extrusion direction, and the raw material needs to be dried. treatment. When there are impurities in the raw material that are difficult to plasticize, some lower pitting will also occur. When the pits are relatively large, you can see the impurities in the middle of the pits. At this time, it is necessary to increase the processing temperature or replace the raw materials.
