Parallel Twin-Screw Extrusion Line (For HDPE/PP Pipes)
- Excellent Mixing & Raw Material Flexibility: Utilizes two parallel co-rotating twin-screw extruders for superior dispersion. Can process both powder and granular raw materials simultaneously without pre-compounding, offering maximum formula flexibility.
- Online Formula Adjustment: Includes a side-feeding system allowing for real-time online adjustment of filler ratios (e.g., calcium powder), facilitating quick and convenient formula changes.
- Modular & Easy Maintenance: The building-block style screw and barrel assembly simplifies maintenance and part replacement, minimizing downtime.
| Type | Pipe Diameter (mm) | HDPE Output (kg/h) | Max Speed (m/min) | Total Power (KW) |
|---|---|---|---|---|

| JWSBL-1200 | 800–1200 | 1400 | 1.5 | 800 |
Horizontal DWC Pipe Line (For Small-Diameter Pipes)
- Compact Solution for Small Pipes: Specifically designed for producing small-diameter DWC pipes (Ø50–250mm), ideal for drainage, venting, and conduit applications.
- High Plasticization & Output: Incorporates a new high-efficiency single-screw extruder that delivers greatly enhanced plasticizing capacity and high output of flexible pipe products.
- User-Friendly Operation: The horizontal structure of the molding machine provides a compact footprint and facilitates easier operation and maintenance.

Frequently Asked Questions
Q
What pipe materials are compatible with these double wall corrugated pipe extrusion lines?
The extrusion lines are designed to accommodate a wide range of thermoplastic materials. The High-Speed Single-Screw and Parallel Twin-Screw lines are optimized for HDPE and PP, the Conical Twin-Screw line handles FRPP and PVC (including direct powder processing), and the Horizontal DWC line is ideal for flexible small-diameter PE pipes.
Q
What pipe diameter range can these extrusion lines produce?
The lines cover a broad diameter spectrum. The Horizontal DWC line handles small-diameter pipes from Ø50mm to Ø250mm, while the larger vertical lines (JWSBL series) can produce pipes ranging from Ø110mm up to Ø1200mm, depending on the selected model configuration.
Q
What makes the forming modules durable and long-lasting?
The forming modules are precision-cast from LY12 high-grade aviation aluminum with a copper content of ≥5%. This ensures high material density, eliminates porosity, and provides strong resistance to long-term deformation under continuous production conditions. The modules also feature excellent interchangeability and support customizable waveform designs.
Q
Can the Conical Twin-Screw line process raw powder directly without pelletizing?
Yes. The Conical Twin-Screw Extrusion Line is specifically capable of processing powder formulas directly — for example, raw PVC or FRPP resin combined with calcium carbonate — without requiring a separate pelletizing step. This significantly reduces raw material costs and enhances the ring stiffness of the finished pipe.
Q
How is the control system configured, and how easy is it to operate?
All extrusion lines are equipped with advanced computer HMI control systems, including industry-leading platforms such as Siemens. The interface provides high automation, precise real-time parameter management, and an intuitive user experience — minimizing operator training time and reducing the risk of human error during production.
Q
What industries and applications are the produced DWC pipes suitable for?
The double wall corrugated pipes produced by these lines serve multiple industries: Municipal & Civil Engineering (stormwater drainage, sewer networks, foundation drainage), Telecommunications & Power (optical fiber conduits, electrical wire protection), Agriculture & Water Conservancy (irrigation pipelines, drainage systems), and Industrial & Environmental Protection (fluid conveyance, mine ventilation, landfill leachate collection).
