40-350mm HDPE double wall corrugated pipe extrusion line for DWC pipe making machine

Double wall corrugated pipe machine for making the pipe from 40-350mm.



Double wall HDPE corrugated pipe machine adopts extruding and forming process, it has the featuresof reliable quality and high efficiency.Compared with other plastic pipe wall structure ,double wall corrugated pipe has excellent wall structure design,its low weight reach the lower production cost and improve the market competitiveness.The pipe is widely used in various field instead of concrete pipe and iron pipes,because it has excellent features such as:easy connected and accessories installed,and quality reliable.

Advantage of our Plastic DWC double wall corrugated pipe machine
1. The main machine adopts special designed high efficiency screw which is specially used for HDPE,it has the features of stable performance and high efficient. The machine has two independence extruder ,which can realize both inside and outside layer with different material and colors.

2. Composite extrusion die head with specially helical structure to make the wall thickness uninfom and stable production.

3. The forming machine has automatic power-off protection device.The forming machine an antumatically exit from the die head to avoid equipment failure in case of electricity cut off suddenly.It also equipped with new type high transmitting ratio reducer,easy to operate and maintain

4. The corrugated forming system is in combination with water cooling and air cooling to ensure high production speed
continuously.Advanced programmable lubricating system minimizes the molds wear so as to increase the life of service and ensure work smoothly with high precision to ensure the products quality stability.

5. Mold adopts specially aluminum alloy material and high precision die casting forming mold method,it has the advantages of high precision,high strength,good wear-ability and better heat dissipation performance.

6. Wave structure launched a comprehensive new optimization design to reach the best combination of high-rigidity and low weight.

Double wall corrugated pipe application
The double-wall corrugated pipe is formed by sintering and extruding the corrugated outer wall and a smooth inner wall
simultaneously extruded by HDPE. The section of the pipe wall is a double-layer structure, the inner wall is smooth and flat, and the outer wall is equirec tangularly arranged with a trapezoidal hollow structure. Pipe. It has excellent ring stiffness, good strength and toughness, light weight, strong impact resistance, not easy to break, etc., and it is easy to transport and install. The pipeline is mainly connected by rubber ring socket (also can be connected by heat shrinkable tape). Due to the special design of the wall structure of the double-wall corrugated pipe, under the condition of the same diameter and the same ring stiffness,the material (HDPE) is the least.

Product specifications are:
DN 40 mm, DN 50 mm, DN 63 mm, DN 75 mm, DN 90 mm, DN 110 mm, DN 125 mm, DN 150 mm, DN 220 mm, DN 225 mm, DN 250 mm, DN 300 mm, DN 400 mm, DN 500 mm, DN 600 mm,DN 700 mm, DN 800 mm, DN 1000 mm, DN 1200 mm, etc.

Advantages of double wall corrugated pipe

·Reasonable structure and beautiful appearance, temperature resistance -40ºC-60ºC, low resistance, large flow, strong flame retardancy ·Long service life, reliable sanitary performance, low overall cost ·Acid and alkali resistance, high strength, shock resistance strong performance. Energy saving and consumption reduction. Convenient installation and transportation
