PE/PP/PVC Single Double Wall Corrugated Pipe Extrusion Line With On-Line Belling

Description of double wall corrugated pipe extrusion line

High density polyethylene (HDPE) double wall corrugated pipe is a new type of pipe with annular structure outer wall and smooth inner wall. It was first developed in Germany in the early 80s. After more than 10 years of development and improvement, it has developed from a single variety to a complete product line.

At present, the production process and the use of technology have been very mature. Because of its excellent performance and relatively economic cost, it has been widely promoted and applied in developed countries, such as Europe and America. In our country, the popularization and application of HDPE double wall corrugated pipe is in the rising stage, and all technical indexes meet the standard of use. The walls of double wall bellows usually have blue and black colors, and some brands use yellow inside the walls.

It is mainly used for large water delivery, water supply, drainage, sewage discharge, exhaust, subway ventilation, mine ventilation, farmland irrigation, etc. under the pressure of less than 0.6MPa. such as:
1. Municipal Engineering: used as drainage pipe.
2. construction works: used as building rainwater pipes, underground drainage pipes, sewage pipes, ventilation pipes.
3. railway, highway communication equipment: used as communication cable, optical cable protection tube.
4. industry: widely used in chemical, hospital, environmental protection industries such as sewage pipes.
5. agricultural garden project: used in farmland, fruit tea garden, and forest belt drain.

6. Road Engineering: used as the seepage and drain pipe of railway and expressway.
7. Mine: used as mine ventilation, air supply, drain pipe.
8. double walled bellows: can do saline, highway seepage, drainage pipe.
9. golf course, football field project: used as a golf course, football field of infiltration, drainage pipe..
