The PE pipe for sewage discharge is also known as high-density polyethylene pipe (HDPE). This kind of pipe is often used as municipal engineering pipe, mainly in the sewage treatment industry. Because of its characteristics of wear resistance, acid resistance, corrosion resistance, high temperature resistance and high pressure resistance, it has gradually replaced the position of traditional pipes such as steel pipes and cement pipes in the market, especially because of its light weight and convenient installation and movement, it is a good choice for new materials.
What kinds of PE drain pipes are available:
1. PE hollow wall winding structure pipe
HDPE hollow wall winding pipe is made of 100% high density polyethylene (HDPE) by special extrusion process in the hot melt state, and welded into a whole pipe.
2. Steel strip reinforced polyethylene (pe) spiral corrugated pipe
The double wall spiral corrugated pipe is made of high density polyethylene (PE) as the matrix, steel tape coated with adhesive resin as the main supporting structure, and wound and compounded with polyethylene material as a whole.
3. HDPE plastic steel winding pipe
4. hdpe solid wall drain pipe
HDPE drain pipe is a general term for thermoplastic circular pipe without internal pressure, which is mainly made of high-density polyethylene resin and is made by extrusion molding process. HDPE drainage pipe is a replacement product of traditional steel pipe and PVC drainage pipe. It mainly undertakes the tasks of rainwater, sewage, farmland drainage and irrigation, and is widely used in highway, railway subgrade, subway engineering, waste landfill, tunnel, green belt, sports ground, slope protection caused by high water content and other drainage fields, as well as underground irrigation and drainage systems for agriculture and horticulture.
5. Double wall corrugated pipe
High density polyethylene (HDPE) double wall corrugated pipe is a new type of pipe with annular outer wall and smooth inner wall. It was first developed in Germany in the early 1980s. After more than ten years of development and improvement, it has developed from a single variety to a complete product series. At present, the production process and application technology are very mature. Because of its excellent performance and relatively economic cost, it has been greatly promoted and applied in Europe, America and other developed countries. In china, the popularization and application of hdpe double wall corrugated pipe is in the rising stage, and all technical indicators have reached the use standard. The inner walls of double wall corrugated pipes are usually blue and black, and some brands use yellow.
