Welcome to Qingdao Yongke Machinery Co., Ltd. Since our establishment in 2010, we have dedicated ourselves to the design and manufacture of high-quality extrusion machinery. Our Spiral Winding Corrugated Pipe Extrusion Machinery is specifically engineered for producing robust pipes used in sewerage systems, culverts, and storage tanks. With over a decade of experience and a factory spanning 10,000–30,000 square meters, we combine advanced technology with rigorous quality control to deliver reliable solutions that meet the demands of modern infrastructure projects.
This machine utilizes a continuous spiral winding process to form corrugated pipes with excellent structural integrity and hydraulic performance. The resulting pipes offer superior resistance to external loads, chemical corrosion, and soil movement, making them ideal for underground drainage, stormwater management, and industrial liquid storage. Our equipment is designed for high efficiency, low energy consumption, and ease of operation, allowing you to produce consistent-quality pipes at competitive costs.
Key Features and Technical Specifications
- Advanced Spiral Winding Technology: The extruder continuously wraps a molten strip of HDPE or PP around a rotating mandrel, forming a seamless corrugated profile. This eliminates the need for separate forming molds and reduces material waste.
- Durable Construction: The machine frame is built from heavy-duty steel, ensuring long-term stability even under high production loads. Key components such as the screw and barrel are made from nitrided alloy steel for extended service life.
- Precise Temperature Control: Multiple heating zones with independent PID controllers maintain accurate melt temperatures, preventing overheating and ensuring uniform plasticization. Cooling fans and water spray systems rapidly set the pipe profile.
- Flexible Pipe Size Range: By adjusting the mandrel diameter and winding speed, the machine can produce pipes with inner diameters from 200 mm up to 1200 mm (or larger upon request). Wall thickness and corrugation depth are also customizable.
- High Production Efficiency: Typical output rates range from 100 to 300 kg/h, depending on pipe size and material. The continuous process minimizes downtime, and the automatic cutting and stacking systems further enhance overall productivity.
- User-Friendly PLC Control: A touch-screen interface allows operators to monitor and adjust parameters such as screw speed, temperature, winding speed, and cooling intensity. Real-time data logging helps maintain consistent quality and supports traceability.

Benefits for Your Production
- Cost Savings: The spiral winding process uses 15–30% less material compared to traditional injection-molded or extruded pipes with equal strength. Energy consumption is optimized through efficient heating and drive systems.
- Versatility: Quickly switch between different pipe diameters and wall thicknesses by changing the mandrel and adjusting process parameters. This flexibility allows you to respond to diverse project requirements without extensive retooling.
- Reliable Performance: Pipes produced on our machinery exhibit excellent ring stiffness (SN2–SN16) and long-term creep resistance. They meet international standards for underground drainage and irrigation applications.
- Low Maintenance: The machine’s modular design simplifies cleaning and parts replacement. High-quality bearings and seals reduce wear, and the control system alerts operators to potential issues before they cause downtime.
- Environmental Compliance: Our extrusion process generates minimal scrap; leftover material can be reground and reused. The finished pipes are 100% recyclable, supporting green building initiatives.
Whether you are establishing a new production line or upgrading existing capacity, our team provides comprehensive support from machine layout to commissioning. We offer optional accessories such as automatic pipe cutters, belling machines, and stacking conveyors to create a complete turnkey solution.

Frequently Asked Questions (FAQ)
Q1: What pipe diameters can your machine produce?
A: Our standard machine can produce pipes with inner diameters from 200 mm to 1200 mm. Larger diameters up to 3600 mm are possible with a customized mandrel and winding head. Please provide your specific requirements for a tailored solution.
Q2: What materials are compatible with this extrusion line?
A: The machine is primarily designed for HDPE (PE80, PE100) and PP materials. It can also process polypropylene random copolymer (PP-R) with slight adjustments to temperature settings. We recommend using virgin or regrind material with a melt flow index (MFI) between 0.2 and 1.0 g/10 min.
Q3: What is the typical output capacity?
A: Output depends on pipe diameter, wall thickness, and material. For a 600 mm diameter pipe with standard wall thickness, the production rate is approximately 3–5 meters per minute, translating to 150–300 kg/h. Maximum capacity can reach 500 kg/h for smaller pipes.
Q4: Do you provide installation and training services?
A: Yes, we offer on-site installation guidance and operator training for all our extrusion lines. Our engineers can supervise the setup and commissioning to ensure a smooth startup. Remote video support is also available for routine adjustments.
Q5: What is the warranty period for this machinery?
A: We provide a standard 12-month warranty from the date of commissioning, covering manufacturing defects in materials and workmanship. Extended warranty plans are available upon request. Spare parts are kept in stock for quick replacements.
Q6: Can the machine produce pipes with integrated bell ends?
A: Yes, we offer an optional belling attachment that forms integral socket ends during the winding process. This eliminates the need for separate couplings and speeds up on-site jointing. Please discuss your requirements with our sales team.
Q7: How do you ensure the quality of the finished pipes?
A: The PLC system continuously monitors critical parameters like melt temperature, winding tension, and cooling rate. Additionally, we can integrate in-line ultrasonic wall thickness gauges and ring stiffness testers for real-time quality assurance. Our factory is ISO9001 certified, and each machine undergoes a full performance test before shipment.
Q8: What are the power requirements for the extrusion line?
A: Typical power consumption is 80–150 kW depending on the configuration. The machine can be designed for 380V/50Hz, 440V/60Hz, or other voltage/frequency combinations as per your local grid. Our electrical team will customize the control panel accordingly.
