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.

| 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 materials can the double wall corrugated pipe extrusion lines process?
The lines are designed to handle a wide range of materials. The High-Speed Single-Screw line is optimized for PE and PP; the Conical Twin-Screw line processes FRPP and PVC (including direct powder formulas with calcium carbonate); and the Parallel Twin-Screw line handles HDPE and PP in both powder and granular form.
What pipe diameter ranges are available across the different extrusion lines?
The lines cover a broad range of pipe diameters. The Horizontal DWC Line handles small-diameter pipes from Ø50mm to Ø250mm. The larger vertical lines (JWSBL series) cover diameters from 110mm up to 1200mm, depending on the model selected.
What is the maximum production output achievable?
Maximum output varies by line type and model. The JWSBL-1200 models across the Single-Screw, Conical Twin-Screw, and Parallel Twin-Screw lines can achieve up to 1,400 kg/h. For PVC specifically, the Conical Twin-Screw JWSBL-1200 also reaches 1,400 kg/h output.
What control system is used, and how automated are the lines?
All extrusion lines are equipped with advanced computer HMI control systems, including industry-leading platforms such as Siemens. This provides a high level of automation, precise real-time parameter management, and an intuitive, user-friendly interface suitable for both experienced operators and new users.
What are the main application fields for pipes produced by these lines?
The double wall corrugated pipes produced are used across multiple industries, including municipal and civil engineering (stormwater drainage, sewer networks), telecommunications and power (cable conduits, wire protection ducts), agriculture and water conservancy (irrigation pipelines), and industrial and environmental protection (fluid conveyance, mine ventilation, landfill leachate collection).
