Qingdao Yongke Machinery Co., Ltd. is proud to present our advanced HDPE Inner Rib Reinforced Spiral Winding Krah Pipe Extrusion Machine. Since our establishment in 2010, we have dedicated ourselves to manufacturing high-quality extrusion equipment for the global plastic piping industry. This machine is specifically engineered to produce large-diameter HDPE spiral wound pipes with inner rib reinforcement, offering exceptional strength-to-weight ratio and long-lasting durability. Our systems are widely trusted by clients across North America, South America, Europe, Southeast Asia, Africa, and Oceania, thanks to their consistent performance, energy efficiency, and ease of operation.
Key Features and Benefits
- Inner Rib Reinforcement Technology: The machine integrates a unique inner rib forming section that creates structural ribs inside the pipe wall, significantly enhancing hoop strength and ring stiffness without increasing material consumption. This results in pipes that can withstand higher soil loads and internal pressure.
- Spiral Winding Process: Our continuous spiral winding system ensures uniform wall thickness and smooth surface finish. The process is fully automated, reducing labor costs and production errors.
- High Output & Energy Saving: With extrusion outputs ranging from 300 to 2000 kg/h (depending on configuration), the machine maintains high productivity while consuming minimal energy due to optimized screw and barrel designs.
- Flexible Pipe Diameter Range: The machine can produce pipes from 200 mm up to 4000 mm in diameter, making it suitable for various applications such as municipal water supply, sewage systems, stormwater drainage, and industrial pipelines.
- Robust Construction: The mainframe is built from heavy-duty steel, and all contact parts are corrosion-resistant. The extruder is equipped with a high-torque gearbox and bimetallic barrel for extended service life.
- Advanced PLC Control: A Siemens-based PLC with a user-friendly touch screen interface allows operators to monitor and adjust parameters in real time. Recipes can be stored for different pipe specifications, ensuring repeatability and quality control.
- Comprehensive After-Sales Support: We provide on-site installation, commissioning, and training, along with a one-year warranty and lifelong technical support. Spare parts are readily available from our Qingdao factory.

Advantages Over Conventional Pipe Production Lines
- Material Savings: The inner rib design reduces raw material usage by up to 20% compared to solid-wall pipes of equivalent stiffness, lowering your production costs.
- Faster Installation: Pipes produced by this machine are lightweight (typically 30–50% lighter than concrete pipes), making handling and installation faster and safer on site.
- Corrosion & Chemical Resistance: HDPE pipes are immune to rust, chemicals, and abrasion, ensuring a service life of 50+ years in demanding environments.
- Leak-proof Joints: The spiral winding process produces continuous lengths with integrated socket-and-spigot ends or electrofusion welding compatibility, eliminating weak points.
- Environmental Compliance: Our machine meets international environmental standards and can process recycled HDPE materials, supporting circular economy goals.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum pipe diameter this machine can produce?
A: The standard machine can produce pipes from 200 mm up to 4000 mm in diameter. Larger diameters are possible with customized molds – please consult our sales engineers. -
Q: Does the machine support automatic control and data logging?
A: Yes, the PLC system with touch screen provides real-time monitoring, parameter setting, and data recording. It also supports remote diagnostics via Ethernet (optional). -
Q: Can the machine produce pipes with different wall thicknesses?
A: Absolutely. By adjusting the take-off speed and extrusion rate, you can achieve wall thicknesses from 10 mm to 200 mm. The die head is designed to handle a wide range of thicknesses without changing hardware. -
Q: What after-sales service do you provide?
A: We offer one-year warranty, free spare parts for initial commissioning, on-site training for your operators, and worldwide technical support via phone, email, or video call. Our service team is available 24/7. -
Q: Is the machine suitable for producing pipes from recycled HDPE?
A: Yes, the extrusion system can handle a blend of virgin and recycled HDPE (up to 30% recycled content, depending on quality). We recommend a melt filtration system for better consistency. -
Q: How long does it take to install and commission the machine?
A: Typical installation and commissioning take 2–4 weeks on site, depending on the complexity of the line and local conditions. Our engineers will supervise the entire process. -
Q: What tests are performed on the finished pipes?
A: We can provide hydrostatic pressure test, ring stiffness test, and dimension inspection as per international standards (e.g., ASTM F894, EN 13476). The machine can be equipped with online quality measuring devices upon request. -
Q: Can the machine be integrated with existing pipe production lines?
A: Yes, our machine can be customized to work with your existing downstream equipment such as cooling tanks, cutters, or bellers. We will adapt the interfaces accordingly.
