Qingdao Yongke Machinery Co., Ltd, a leading manufacturer with over a decade of expertise, proudly introduces our Krah Helical Extrusion Pipe Production Line with PLC Control (380V, 50Hz, 45kW Motor). This advanced production system is engineered to deliver high-quality spiral-wound pipes used in drainage, sewerage, and industrial applications. With our ISO9001-certified facility spanning 10,000–30,000 square meters and a dedicated team of 51–100 employees, we ensure every line meets rigorous standards for performance and reliability. The integrated PLC control allows precise automation, reducing labor costs and increasing output consistency.
The Krah helical extrusion process is a proven method for producing large-diameter plastic pipes with superior structural integrity. Our line combines a robust 45kW motor with a helical winding head, enabling seamless production of pipes from HDPE or PP materials. The PLC system monitors critical parameters such as temperature, pressure, and winding speed, ensuring uniform wall thickness and exceptional mechanical strength. This makes it ideal for applications like stormwater management, underground drainage, and chemical transportation.
Key Features & Technical Specifications
- High-Efficiency Extrusion: The 45kW motor provides ample power for continuous operation, achieving output rates of up to 600 kg/h (depending on material and pipe size).
- PLC Touchscreen Control: User-friendly interface allows real-time monitoring and adjustment of all process parameters. Recipes can be stored for different pipe specifications.
- Helical Winding Head: Precision-engineered to produce pipes with a smooth inner surface and ribbed outer profile, enhancing structural strength and hydraulic performance.
- Automatic Cooling System: Multi-stage water cooling ensures uniform solidification, preventing deformation and maintaining dimensional accuracy.
- Haul-Off & Cutting Unit: Synchronized servo-driven haul-off with automatic cutting to length (customizable from 1m to 12m).
- Energy-Saving Design: Variable frequency drives (VFDs) on main motors reduce power consumption during partial load operation.

Beyond the technical specs, our production line offers tangible benefits to your business. The PLC control reduces operator intervention by 30%, while the energy-efficient design lowers electricity costs by up to 15% compared to conventional systems. The modular construction allows easy integration with existing extrusion lines or downstream equipment. Additionally, the helical winding technology minimizes material waste, as the continuous process eliminates the need for separate jointing steps.
Service life is a key consideration. All components are sourced from reputable suppliers, and the frame is built from heavy-duty steel with anti-corrosion treatment. The entire line is backed by our experienced engineering team, available for on-site installation and training. With our factory located in Qingdao, China, we offer efficient logistics to ports worldwide, ensuring timely delivery.
