PE HDPE double wall corrugated pipe production line

PE double wall corrugated pipe has the characteristics of light weight, high pressure resistance, good toughness, fast construction and long service life. In addition to the good corrosion resistance, high insulation, smooth inner wall and small flow resistance of ordinary plastic pipes, it also Due to the special hollow ring structure, it has excellent ring stiffness, good strength and toughness, light weight, strong impact resistance, and is not easy to break. Double-wall corrugated pipes are widely used in municipal drainage, agricultural irrigation, coal mine ventilation, chemical industry, communication cable sheathing and other fields. Practice has proved that the use of double-wall corrugated pipe structure can save 30%-50% of raw materials under the condition of meeting the strength and stiffness requirements of engineering applications. In addition, compared with concrete pipes and cast iron pipes, it is convenient for transportation and installation, reducing the labor intensity of construction personnel and reducing Due to the advantages of the total investment of the project, the double-wall corrugated pipe has become the preferred pipe material for “replacing steel with plastic” in the pipeline field. Shortcomings.

Since PE double-arm corrugated pipes are usually large-sized pipes, they are usually produced by twin-screw extruders. The production process mainly includes two stages: raw materials mixing and extrusion.  Commonly used PE double wall corrugated pipe sizes include: DN110mm, DN125, DN150, DN220, DN225mm, DN250, DN300mm, DN400mm, DN500mm, DN600mm, DN700mm, DN800, DN1000, DN1200 and so on.

Main features of PE HDPE double wall corrugated pipe production line: 

1. The sealed pressure water-cooled corrugated forming module greatly improves the production speed.
2. Lower energy consumption, significantly reducing the cost of pipe production.
3. Efficient vacuum system to form perfect pipes.
4. The module temperature control system further optimizes the pipe quality.
5. It is easy and fast to change the mold.
6. The entire production line is fully automated.
7. The molding machine and the extruder are controlled synchronously.
