In the drainage and water supply system, pipes are an important part of it, so the quality of pipes plays a decisive role. From past experience, compared with plastic or metal pipes, pe pipes have the following characteristics:

① Low density, high strength, good toughness;

② It is corrosion-resistant, easy to color, and has good insulation properties.

③ Convenient construction, simple and quick installation, and low maintenance cost.

Based on these three advantages of PE pipe, it can be used in water supply and drainage systems, agricultural irrigation water, mineral transportation in mines, and gas heating.

After a brief understanding of the advantages of PE pipes, let’s list its application status quo. In developed countries and regions abroad, PE pipes account for more than 90% of inter-city buried gas pipelines, and the market share of water supply pipes has reached 60%, and foreign countries have established very mature PE pipes. The standard construction specification. As galvanized pipes are gradually banned in China, PE pipes have a competitive advantage in the fields of building water supply. In industries such as gas, industrial water supply, communications, and agricultural irrigation, PE pipes are also showing a rapid growth trend. The pipe standards and specifications have not kept up, which has affected the application and development of PE pipes to a certain extent.

There are many classification methods for PE pipes, and there are different classification methods according to different standards. According to the purpose, it can be divided into construction and municipal water supply and drainage pipes, outdoor gas pipes, agricultural irrigation pipes, threading pipes, sewage pipes, etc. According to pipe quality and structure, PE pipes can be divided into ordinary PE pipes, aluminum-plastic composite pipes, steel-plastic composite pipes, steel-plastic composite pipes, reinforced pipes, single/double-wall corrugated pipes, spiral pipes, silicon core pipes for optical cables, etc. . According to the density of raw materials, it can be divided into high-density tubes, low-density tubes and medium-density tubes.
