Qingdao Yongke Machinery Co., Ltd., established in 2010, is a professional manufacturer specializing in the design and production of plastic pipe extrusion lines. With over a decade of experience and a factory spanning 10,000-30,000 square meters, we are proud to introduce our High Speed Forming Double Wall Corrugated Pipe Extrusion Line – a state-of-the-art solution engineered for municipal drainage pipe fabrication. This line combines advanced forming technology with robust mechanical design, delivering high output efficiency and consistent pipe quality. Whether you need pipes for stormwater drainage, sewer systems, or cable protection, our extrusion line offers the reliability and performance you can trust.
The core advantage of this extrusion line lies in its high-speed forming system. Using a specially designed vacuum calibrator and continuous corrugation mold, the machine can produce double wall corrugated pipes with a smooth inner wall and a corrugated outer wall at speeds up to 6 meters per minute. This not only boosts production capacity but also reduces energy consumption per meter. The line is fully compatible with HDPE and PP materials, ensuring excellent ring stiffness and impact resistance – critical for underground drainage applications.

Product Features & Benefits
High-Speed Forming Technology: The advanced corrugation mold and vacuum calibration system enable rapid pipe forming, increasing production efficiency by up to 30% compared to conventional lines.
Double Wall Structure: Smooth inner wall reduces fluid friction, while corrugated outer wall provides excellent ring stiffness (SN8 to SN16) for underground load-bearing.
Energy-Efficient Extruders: Equipped with high-torque, low-noise gearboxes and frequency inverters, the extruders consume less power while maintaining stable output.
Precise Temperature Control: Multi-zone PID temperature controllers ensure uniform melt temperature, minimizing material degradation and optimizing pipe quality.
User-Friendly PLC Control: Siemens or Mitsubishi PLC system with touchscreen interface allows one-person operation, real-time monitoring, and parameter storage for different pipe specifications.
Durable Construction: All components in contact with plastic are made of hardened stainless steel or nitrided alloy, ensuring long service life and low maintenance.
Quick Mold Change: The corrugation molds are designed for fast and easy replacement, reducing downtime during diameter changeovers.
Integrated Cooling & Cutting: The line includes a high-efficiency water spray cooling system and a servo-driven planetary cutter for precise length cutting (optional automatic stacker).
Our double wall corrugated pipe extrusion line is widely used in municipal drainage, stormwater management, sewage systems, and cable protection. The pipes produced meet international standards such as EN 13476, ISO 9001, and are proven in projects across North America, Europe, Southeast Asia, Africa, and Oceania. With a production capacity of 300-600 kg/h, a single line can produce 800-1,500 meters of DN/ID 200-600 pipe per day, significantly reducing per-unit cost.

Frequently Asked Questions
Q1: What materials can this extrusion line process?
A: The line is designed for HDPE (high-density polyethylene) and PP (polypropylene). It can also be adapted for other thermoplastic materials upon request.
Q2: What is the pipe diameter range?
A: Standard range is from 200 mm to 1600 mm. Custom sizes outside this range are available with mold modifications.
Q3: How long does mold change take?
A: With our quick-change system, a mold change can be completed within 2-3 hours by two trained operators.
Q4: What is the typical power consumption per meter of pipe?
A: Power consumption varies with pipe size and material, but typically ranges from 0.8 to 1.5 kWh per meter for DN/ID 400-600 pipes.
Q5: Do you provide installation and training?
A: Yes, we offer on-site installation, commissioning, and training for your operators. Remote support via video call is also available.
Q6: What is the warranty period?
A: The standard warranty is 12 months from the date of commissioning or 18 months from shipment, whichever comes first. Extended warranties are optional.
Q7: Can the line be integrated with a downstream pipe belling or socketing machine?
A: Yes, we can supply an optional socketing machine, gasket fitting unit, and leak tester to form a complete production line.
Q8: What certifications does your company hold?
A: We are certified under ISO9001 (Quality Management), ISO14000 (Environmental Management), and OHSAS18001 (Occupational Health & Safety). Our machines also comply with CE standards upon request.
