Frequently Asked Questions
โ
What materials can the double wall corrugated pipe extrusion lines process?
The extrusion 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. The Horizontal DWC line also supports flexible PE/PP pipe production for small diameters.
โ
What pipe diameter range is covered across all available lines?
The product range covers pipes from ร50mm up to ร1200mm. The Horizontal DWC line handles small diameters from ร50mm to ร250mm, while the vertical extrusion lines (Single-Screw, Conical Twin-Screw, and Parallel Twin-Screw) cover ร110mm to ร1200mm, with specific models suited to each diameter range.
โ
What control system is used on these extrusion lines?
All lines are equipped with advanced computer HMI control systems, including industry-leading brands such as Siemens. This ensures high levels of automation, precise parameter management, real-time monitoring, and user-friendly operation โ reducing operator workload and improving production consistency.
โ
Can the forming modules be customized for different pipe profiles?
Yes. The forming modules are manufactured from precision-cast LY12 high-grade aviation aluminum (copper content โฅ5%), ensuring high density and resistance to long-term deformation. They offer excellent interchangeability between compatible models and support fully customizable waveform designs to meet specific pipe profile or project requirements.
โ
What are the main application industries for double wall corrugated pipes produced by these lines?
Double wall corrugated pipes produced by these lines are widely used in Municipal & Civil Engineering (stormwater drainage, sewer networks), Telecommunications & Power (fiber optic conduits, cable protection), Agriculture & Water Conservancy (irrigation pipelines, drainage systems), and Industrial & Environmental Protection (fluid conveyance, mine ventilation, landfill leachate collection).
โ
Does the Conical Twin-Screw line require pelletized raw materials, or can it use powder directly?
The Conical Twin-Screw Extrusion Line is specifically designed to process powder formulas directly โ for example, a blend of raw resin and calcium carbonate โ without any need for pre-pelletizing. This capability significantly reduces raw material processing costs while also enhancing the ring stiffness of the finished pipe, making it a highly cost-effective solution for PVC and FRPP pipe production.
