Frequently Asked Questions
QWhat materials can the double wall corrugated pipe extrusion lines process?
The lines are designed to process a range of thermoplastic materials including HDPE, PE, PP, FRPP, and PVC. The High-Speed Single-Screw line is optimized for PE/PP, the Conical Twin-Screw line handles FRPP and PVC, and the Parallel Twin-Screw line is suited for HDPE and PP applications.
QWhat pipe diameter range can these extrusion lines produce?
The lines cover a wide diameter range to meet diverse project needs. The Horizontal DWC line handles small diameters from ร50mm to ร250mm, while the larger vertical lines (JWSBL series) can produce pipes from ร110mm up to ร1200mm, depending on the model selected.
QCan 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 โ for example, a blend of raw resin and calcium carbonate โ without requiring a separate pelletizing step. This significantly reduces raw material costs and also enhances the ring stiffness of the finished pipe.
QWhat 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 production parameters, monitor line status in real time, and benefit from intuitive, user-friendly controls that reduce the skill threshold for operators.
QWhat industries are the produced double wall corrugated pipes suitable for?
The DWC pipes produced by these lines are widely used across multiple industries: municipal and civil engineering (stormwater drainage, sewer networks), telecommunications and power (fiber optic conduits, electrical wire protection), agriculture and water conservancy (irrigation pipelines), and industrial and environmental protection applications (fluid conveyance, mine ventilation, landfill leachate collection).
QWhat kind of after-sales and technical support is provided?
JWELL provides comprehensive technical support backed by extensive industry experience. This includes professional guidance on line configuration and selection, assistance with production startup and optimization, operator training, and ongoing after-sales service to ensure long-term, stable, and high-output production performance.
