High Speed Double Wall Corrugated Pipe Production Line | HDPE DWC Pipe Extrusion Machine

Welcome to our High Speed Double Wall Corrugated Pipe Production Line, a next-generation extrusion solution designed for manufacturing high-quality HDPE and PP double wall corrugated pipes with exceptional speed, precision, and reliability.

Developed with advanced European corrugation technology and intelligent automation, this Double Wall Corrugated Pipe Extrusion Line is widely used for producing municipal drainage pipes, sewer pipes, stormwater pipes, cable protection ducts, electrical conduit pipes, telecommunications conduits, and underground infrastructure systems.

As an experienced Double Wall Corrugated Pipe Machine Manufacturer, we continuously improve our extrusion technology to help customers achieve higher output, lower energy consumption, and superior pipe quality.

High-Efficiency Extrusion System

The production process begins with an automatic material feeding system. HDPE or PP raw materials are transported into two high-performance single screw extruders.

The co-extrusion design allows the inner and outer pipe layers to be produced simultaneously. This technology improves pipe strength while reducing raw material consumption and production costs.

Each extruder is equipped with an energy-saving motor, optimized barrier screw, and precision temperature control system.

The specially designed screw provides excellent plasticizing performance, stable melt pressure, and high output, making the machine suitable for continuous high-speed production.

Multiple independent heating zones ensure accurate temperature control, while intelligent cooling fans maintain stable processing conditions throughout the entire extrusion process.

Precision Co-Extrusion Die Head

The molten material flows into the precision co-extrusion die head.

The optimized flow channel distributes polymer evenly, producing pipes with:

· Smooth inner walls

· Uniform wall thickness

· Excellent concentricity

· Strong corrugated outer profiles

The balanced die design minimizes melt pressure fluctuation while improving product consistency during high-speed production.

Different pipe sizes can be produced simply by replacing the die head and corrugator molds.

Horizontal High-Speed Corrugator

The core equipment of the production line is the Horizontal High-Speed Corrugator Machine.

Unlike conventional corrugators, this advanced forming system adopts a fully enclosed horizontal structure with synchronized mold movement.

Precision guide rails ensure stable mold operation while minimizing vibration at high production speeds.

The aluminum alloy mold blocks are manufactured using high-precision CNC machining.

Their excellent thermal conductivity allows rapid cooling and significantly increases production efficiency.

Vacuum forming technology accurately shapes the corrugated outer wall while maintaining a perfectly smooth inner layer.

The result is a lightweight pipe with outstanding ring stiffness and excellent mechanical performance.

Compared with traditional corrugators, the horizontal corrugator offers:

· Higher production speed

· Better cooling efficiency

· Lower maintenance costs

· Longer mold service life

· More stable operation

· Reduced energy consumption

Intelligent Cooling and Vacuum System

The production line features an intelligent vacuum calibration and water cooling system.

Multiple cooling circuits rapidly solidify the molten polymer while maintaining accurate pipe dimensions.

The closed-loop water circulation system reduces water consumption and ensures environmentally friendly production.

Automatic temperature monitoring continuously adjusts cooling efficiency according to production speed.

This guarantees excellent pipe quality even during long-term continuous operation.

Servo-Controlled Haul-Off and Cutting

After forming, the finished pipe enters the synchronized haul-off system.

Servo motors automatically match the extrusion speed, preventing pipe deformation while maintaining dimensional accuracy.

The online cutting machine performs burr-free cutting without interrupting production.

Pipe length can be programmed directly through the touchscreen interface.

Finished pipes are automatically transferred to the receiving table or stacking system, reducing manual labor and improving production efficiency.

Smart PLC Automation

The entire High Speed Double Wall Corrugated Pipe Production Line is controlled by an advanced PLC automation system.

Operators can monitor:

· Extruder temperature

· Screw speed

· Melt pressure

· Vacuum pressure

· Cooling water temperature

· Corrugator speed

· Energy consumption

· Production output

· Alarm status

The Human Machine Interface (HMI) provides intuitive operation and stores production recipes for different pipe specifications.

Remote diagnostics and Industry 4.0 connectivity are also available for smart factory integration.
