Final Product Introduction:


HDPE double-wall corrugated pipes are produced by HDPE double wall corrugated pipe production line, which is extruded by the inner and outer extruders respectively, and formed at one time. tubing. The product has the advantages of high ring stiffness, high strength, light weight, sound insulation and shock absorption, high UV resistance stability, long service life, good flexibility, pressure resistance, and high impact strength. It can be laid on roads with poor geology, and has good sealing performance and quick construction.

Final Product Introduction:

1. The HDPE double wall corrugated pipe production line is equipped with two extruders, double-layer co-extrusion, the extrusion material is stable, and the plasticization is excellent.

2. The imported proportional control valve adjusts the molding air pressure, which is stable and reliable.

3. Double-channel spiral composite extrusion die, the surface of the die is nitrided and polished.

4. Double wall thickness adjustment device.

5. Pipe online double-layer socket and flaring.

6. The horizontal and vertical directions of the workbench are three-dimensionally adjustable.

7. The power off of the workbench will automatically exit the protection system.

8. The module is made of special aluminum alloy, which has the characteristics of light weight, high strength, good wear resistance and small thermal expansion coefficient.

9. The forming module is air-cooled and water-cooled, the cooling effect is good, and the forming speed is fast.

10. The whole double wall corrugated pipe production line adopts PLC microcomputer control system, which can directly display melt temperature, pressure, molding speed, fault alarm, etc.

11. High-efficiency single-screw extruder (using pellets) and energy-saving twin-screw extruder (using powder or pellets) are available.
