Frequently Asked Questions
QWhat pipe materials and diameters can these DWC extrusion lines process?
The lines cover a broad range of materials โ including HDPE, PE, PP, PVC, and FRPP โ and support pipe diameters from ร50mm up to ร1200mm. Different line configurations (single-screw, conical twin-screw, or parallel twin-screw) are optimized for specific materials and diameter ranges to ensure the best output quality and efficiency.
QWhat is the maximum production output of these extrusion lines?
Output capacity varies by line type and model. The high-speed single-screw line reaches up to 1,400 kg/h (JWSBL-1200), the conical twin-screw line achieves up to 1,400 kg/h for both PVC and FRPP, and the parallel twin-screw line also delivers up to 1,400 kg/h HDPE output โ making them suitable for large-scale, continuous industrial production.
QCan the conical twin-screw line process raw powder directly without pelletizing?
Yes. The conical twin-screw extrusion line is specifically designed to process powder formulas directly โ for example, PVC or FRPP resin combined with calcium carbonate filler โ without the need for a separate pelletizing step. This significantly reduces raw material costs and can enhance the ring stiffness of the finished pipe.
QWhat control system is used, and how automated are these lines?
All extrusion lines are equipped with advanced computer HMI control systems, such as Siemens, providing a high level of automation. Operators can precisely monitor and adjust key parameters including temperature, screw speed, haul-off speed, and cutting length โ all from a centralized, user-friendly interface. The automatic DWC cutter also uses computer control for accurate and consistent pipe lengths.
QWhat industries and applications are double wall corrugated pipes used in?
DWC pipes produced by these lines are widely used across municipal & civil engineering (stormwater drainage, sewer systems), telecommunications & power (fiber optic conduits, cable protection), agriculture & water conservancy (irrigation, drainage), and industrial & environmental protection (fluid conveyance, mine ventilation, landfill leachate collection).
QAre the forming modules interchangeable, and can waveform designs be customized?
Yes. The forming modules used in the single-screw line are precision-cast from LY12 high-grade aviation aluminum (copper content โฅ5%), ensuring high density and resistance to long-term deformation. They offer excellent interchangeability across compatible machine models, and custom waveform designs can be manufactured to meet specific project or customer requirements.
