Production desciption
PE/HDPE/PVC double wall corrugated pipe extrusion line 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 accessiories installed,and quality reliable.

SBWG series double - wall corrugated pipe production line can continuously produce HDPE double - wall corrugated pipe and this line can achieve on-line belling.
The machine has the function of automatic demoulding when power is off.
The extruder adopt high-efficiency screw, the die head adopts double-layer spiral structure, mould die and core die being nitrided
The forming machine adopts vacuum forming type, equipped with automatic lubrication system.Forming mould is made of aluminiumalloy, adopt water cooling type.
The pipe can be cut by on-line cutting machine automatically.

Our double wall corrugated pipe machine can use the  aluminum module which with water cooling can vacuum cooling for high speed.We have professional designers and sophisticated processing machine to ensure the accuracy of the mould block.

HDPE double wall corrugated tube dwc pipe making machine series

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 polyolefin,it has the features of stable performance and high effiency.The machine has two independence extruders,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 unifom and stable production.

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

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

5. Mould adopts specialy alumium alloy material and high precision die casting forming mould method,it has the advanages of high precision,high stremgth,good wearability 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
HDPE double wall corrugated pipe 

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 equirectangularly 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:
DN40, DN50mm, DN63mm, DN75mm, DN90mm, DN110mm, DN125mm, DN150mm, DN220mm, DN225mm, DN250mm, DN300mm, DN400mm, DN500mm, DN600mm, DN700mm, DN800mm, DN1000mm, DN1200mm, etc.
