Core Features and Technical Advantages
- Spiral Winding Technology: Utilizes a continuous spiral winding process to form a hollow wall structure, significantly reducing material consumption while maintaining high ring stiffness (SN4–SN16).
- HDPE Material Compatibility: Designed exclusively for HDPE (High Density Polyethylene), ensuring excellent chemical resistance, flexibility, and impact strength even at low temperatures.
- Large Diameter Range: Capable of producing pipes from DN200 up to DN3500 mm, meeting diverse project requirements from culverts to large-diameter stormwater mains.
- Energy-Efficient Extrusion System: Equipped with high-torque, variable-frequency drive extruders that optimize power consumption and melt homogeneity, leading to stable output and lower operating costs.
- Precision Cooling and Calibration: Multi-stage cooling tanks and vacuum calibration ensure accurate dimensional tolerances (±1 mm on diameter) and uniform wall thickness.
- Automated Control System: PLC-based touch screen interface with real-time monitoring of temperature, speed, and pressure; data logging and remote diagnostics available upon request.
- Modular Design: Components such as the winding drum, cutter, and stacker can be customized for specific pipe lengths and production layouts, offering flexibility for factory expansion.

Benefits for Your Business
- Reduced Material Cost: The hollow wall design uses up to 30% less resin compared to solid wall pipes of equivalent stiffness, directly lowering raw material expenditure.
- Higher Production Efficiency: Continuous spiral winding eliminates the need for separate welding or jointing, accelerating the manufacturing cycle and increasing daily output.
- Excellent Hydraulic Performance: Smooth inner surface and optimized wall structure reduce friction loss, enhancing flow capacity in drainage applications.
- Durability and Longevity: HDPE is resistant to chemicals, abrasion, and UV degradation; pipes manufactured on this line can serve for 50+ years under proper conditions.
- Ease of Installation: Lightweight pipes (e.g., a DN1200 pipe weighs only about 60 kg/m) reduce transportation and handling costs, and allow quick trench installation.

Frequently Asked Questions
-
Q: What pipe diameters can this line produce?
A: The line covers DN200 to DN3500 mm. Different winding drum designs can be provided for specific diameter ranges. -
Q: Is the wall structure truly hollow?
A: Yes, the spiral winding process creates a continuous hollow wall profile, which saves material while maintaining high ring stiffness. -
Q: Can the line produce pipes with different stiffness classes?
A: Absolutely. By adjusting the winding speed, material thickness, and profile design, you can achieve SN4, SN8, SN12.5, or SN16 ring stiffness classes. -
Q: What kind of after-sales support do you offer?
A: We provide on-site installation supervision, operator training, and remote technical support. Spare parts are available for quick delivery. -
Q: Do you offer customized voltage and frequency?
A: Yes, the electrical system can be customized to match local voltage (e.g., 380V/50Hz, 460V/60Hz, or 480V/60Hz) as per your requirements. -
Q: How long is the warranty period?
A: Typically 12 months from the date of shipment or 18 months from installation (whichever comes first). Extended warranty options are available. -
Q: Can I produce colored pipes?
A: Yes, HDPE color masterbatch can be added to the extrusion process to produce pipes in various colors (commonly black, blue, or orange). -
Q: Is the control system user-friendly?
A: The PLC system features a touch-screen interface with intuitive menus. We also provide an operation manual and on-site training.
