    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

    Q What materials can the double wall corrugated pipe extrusion lines process?
    The lines are designed to handle a wide range of thermoplastic 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 is suited for HDPE and PP in both powder and granular forms.
    Q What pipe diameter range can these extrusion lines produce?
    The lines cover a broad diameter range to meet diverse project requirements. The Horizontal DWC line handles small-diameter pipes from Ø50mm to Ø250mm, while the larger single-screw, conical twin-screw, and parallel twin-screw lines cover diameters from 110mm up to 1200mm, depending on the model selected.
    Q How does the Conical Twin-Screw line reduce raw material costs?
    The Conical Twin-Screw Extrusion Line can process powder formulas directly — for example, mixing raw resin with calcium carbonate filler — without requiring a separate pelletizing step. This eliminates the energy and equipment costs associated with pre-compounding, directly lowering raw material expenses while also enhancing the ring stiffness of the finished pipe.
    Q What control system is used, and how automated are the lines?
    All extrusion lines are equipped with advanced computer HMI (Human-Machine Interface) control systems, such as Siemens, providing a high level of automation. Operators can precisely manage all key production parameters — including temperature, speed, and cutting length — from a centralized, user-friendly interface, minimizing manual intervention and ensuring consistent product quality.
    Q What industries are the produced double wall corrugated pipes suitable for?
    The DWC pipes produced by these lines are widely used across multiple sectors: municipal and civil engineering (stormwater drainage, sewer networks), telecommunications and power (fiber optic conduits, cable protection ducts), agriculture and water conservancy (irrigation and drainage systems), and industrial and environmental protection applications (fluid conveyance, mine ventilation, landfill leachate collection).
    Q Are the forming modules durable and can they be customized?
    Yes. The forming modules used in the High-Speed Single-Screw line are precision-cast from LY12 high-grade aviation aluminum with a copper content of ≥5%. This ensures high density, zero porosity, and strong resistance to long-term deformation. The modules also feature excellent interchangeability between units and support customizable waveform designs to meet specific pipe profile requirements.
