PE pipes transport sewage for a long time, is the inner wall easy to scale and block?

In the field of sewage transportation, the long-term stable operation of pipelines is crucial, and scaling and blockage are common problems that affect the efficiency and life of pipelines. Many users will pay attention to the performance of PE pipes when choosing sewage transportation pipelines, especially whether the inner wall is prone to scaling and blockage after long-term use.

PE pipes, that is, polyethylene pipes, are not prone to scaling and blockage on the inner wall during long-term transportation of sewage, which is mainly due to their own excellent material properties and inner wall structure. First of all, the inner wall of PE pipes is very smooth. This smooth surface greatly reduces the frictional resistance of fluids during transportation, and also reduces the chance of dirt, microorganisms and other impurities adhering and depositing on the pipe wall. Compared with some pipe materials with relatively rough inner walls, the smoothness of the inner wall of PE pipes makes it more difficult for suspended particles and colloidal substances in sewage to stay, thus effectively inhibiting the formation of scale layers.

Secondly, PE materials have excellent chemical stability. The composition of sewage is complex and may contain a variety of chemical substances such as acids, alkalis, salts, etc., but PE pipes have strong corrosion resistance to these chemical media and are not prone to chemical reactions to generate precipitation or attachments. This stability ensures that the inner wall of PE pipes can still maintain its original smooth characteristics and structural integrity after long-term contact with sewage, further reducing the possibility of fouling.

Of course, although the PE pipe itself is not easy to scale and clog, in practical applications, if the sewage contains a large number of coarse solid impurities, fibers or other materials that are easy to wind and accumulate, it may still cause blockage in local positions such as pipe elbows and valves. Therefore, in order to ensure the long-term stable transportation of sewage by PE pipes, it is necessary to properly pretreat the sewage at the source to remove large particle impurities, and regularly inspect and maintain the pipeline, such as removing a small amount of sediment that may exist by means of flushing.

To sum up, PE pipes have the advantages of smooth inner wall and good chemical stability, and are not easy to scale and clog when transporting sewage for a long time. It is an ideal sewage pipeline material. Under the premise of correct installation, rational use and regular maintenance, it can effectively ensure the smooth and efficient operation of the sewage conveying system.
