[0002] PE sewage pipe is a type of plastic pipe commonly used in municipal, industrial and agricultural drainage systems. It has many outstanding features and a wide range of applications. PE sewage pipe, also known as polyethylene sewage pipe, occupies an important position in modern drainage systems due to its material properties and structural design. In terms of application areas, PE sewage pipes are widely used. They can not only be used in municipal drainage, apartments, and underground buried drainage and sewage systems in residential areas, but also in farmland irrigation, chemical industry, mining and other fields. In addition, pre-buried pipelines on highways and underground seepage pipe networks in golf courses are also common application scenarios.
