| JWSBL-1200 | 800–1200 | 1400 | 1400 | 1.5 |
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-600 | 200–600 | 800 | 5 | 500 |
| JWSBL-1000 | 200–1000 | 1200 | 2.5 | 710 |
| 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
What pipe materials are compatible with these DWC extrusion lines?
The product range covers three main extrusion technologies to accommodate different materials. The high-speed single-screw line is optimized for PE and PP pipes, the conical twin-screw line handles FRPP and PVC pipes, and the parallel twin-screw line is designed for HDPE and PP. This ensures the right solution for virtually every corrugated pipe application.
What pipe diameter ranges can these lines produce?
The lines cover a wide range of pipe diameters. The horizontal DWC line handles small diameters from Ø50 to 250mm, while the larger vertical lines (JWSBL series) can produce pipes from 110mm up to 1200mm in diameter, making them suitable for everything from cable conduits to large municipal drainage systems.
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 material combined with calcium carbonate — without requiring a separate pelletizing step. This significantly reduces raw material costs and also enhances the ring stiffness of the finished pipes.
What control system is used on these extrusion lines?
All lines are equipped with advanced computer HMI (Human-Machine Interface) control systems, including industry-leading platforms such as Siemens. This provides a high degree of automation, precise parameter monitoring and adjustment, and a user-friendly interface that simplifies day-to-day operation and reduces the need for highly specialized operators.
What makes the forming modules durable for long-term production?
The forming modules are precision-cast from LY12 high-grade aviation aluminum with a copper content of ≥5%. This material ensures high density, zero porosity, and strong resistance to long-term deformation under continuous production conditions. The modules also offer excellent interchangeability and can be customized with different waveform designs to meet specific product requirements.
What industries are the finished DWC pipes used in?
The double wall corrugated pipes produced by these lines serve a broad range of industries. Key application areas include municipal and civil engineering (stormwater and sewer drainage), telecommunications and power (fiber optic conduits and wire protection ducts), agriculture and water conservancy (irrigation and drainage pipelines), and industrial and environmental protection (fluid conveyance, mine ventilation, and landfill leachate collection).
