Product Overview
As a leading manufacturer at Qingdao Yongke Machinery Co., Ltd., we introduce our high-performance Spiral Winding Machine specifically designed for HDPE Krah Structured Wall Drainage Pipe extruder lines. With over a decade of industry experience since 2010, our team of 51–100 skilled employees operates in a factory spanning 10,000–30,000 square meters, delivering reliable equipment to global markets. This machine is crafted to produce robust, lightweight, and cost-effective structured wall pipes that excel in drainage and sewer applications. Our commitment to quality is backed by ISO9001, ISO14000, and OHSAS18001 certifications, ensuring every machine meets rigorous international standards. The spiral winding technology enables continuous production of large-diameter pipes with exceptional ring stiffness and hydraulic efficiency, making it an ideal choice for infrastructure projects worldwide.
Key Features & Technical Specifications
- High-Efficiency Winding System: The machine utilizes a precision-controlled spiral winding head that ensures uniform wall structure and consistent pipe diameter. This results in superior strength-to-weight ratio and reduced material consumption.
- Robust Extruder Integration: Seamlessly connects with single-screw extruders (60–120 mm screw diameter) to melt and feed HDPE material directly. The melt temperature and pressure are continuously monitored for optimal processing.
- Flexible Pipe Size Range: Capable of producing pipes with inner diameters from 200 mm to 3000 mm and wall thickness up to 100 mm. The winding mandrel can be easily adjusted or replaced to accommodate different sizes.
- Advanced Cooling & Calibration: Equipped with a multi-zone water spray cooling system and vacuum calibration tank to quickly solidify the pipe and maintain dimensional accuracy. The cooling length is customizable based on pipe wall thickness.
- User-Friendly PLC Control: The Siemens or Mitsubishi PLC system provides intuitive touchscreen operation, real-time data logging, and recipe storage for repeatable production. Parameters such as winding speed, extruder screw speed, and cooling water temperature can be precisely set.
- Durable Construction: All contact parts are made of stainless steel or hardened alloy steel to resist corrosion and wear. The machine frame is built with heavy-duty steel beams for long-term stability.
- Energy-Saving Design: The servo-driven winding mechanism reduces power consumption compared to traditional hydraulic systems. The extruder is equipped with energy-efficient motors and barrel insulation.
- Low Maintenance Requirements: Modular design simplifies access to key components such as bearings, gears, and seals. Automatic lubrication system extends service intervals.

Benefits for Your Production
- Increased Output: Continuous spiral winding process eliminates idle time, boosting daily production capacity by up to 30% compared to batch methods.
- Material Savings: The structured wall design uses up to 40% less raw material than solid wall pipes while maintaining equal strength, reducing your overall material cost.
- Superior Pipe Performance: Pipes produced have excellent ring stiffness (SN2 to SN16) and hydraulic smoothness, meeting international standards like EN 13476 and ASTM F2648.
- Easy Operation: The PLC system with recipe management allows quick changeovers between different pipe sizes, minimizing downtime and labor training.
- Global Compatibility: Our machines are designed to work with 50/60 Hz electrical systems and can be fitted with European or American connectors upon request.

Frequently Asked Questions (FAQ)
-
Q: What is the recommended HDPE material grade for this machine?
A: We recommend using HDPE pipe grade materials with a melt flow index (MFI) between 0.2 and 1.0 g/10min (190°C/5kg). Common grades include PE80 and PE100. Your supplier can provide specific data sheets. -
Q: Can the machine produce pipes with integrated bell-and-spigot joints?
A: Yes, an optional bell-forming unit can be integrated into the line to create bell ends or spigots directly during the winding process. Please contact us for customization details. -
Q: What is the typical power consumption per meter of pipe produced?
A: Power consumption depends on pipe size and wall thickness. For a 600 mm ID pipe with 20 mm wall thickness, approximate consumption is 15–20 kWh per meter. Energy-saving features help reduce overall cost. -
Q: Do you offer training for operators?
A: Yes, we provide on-site training at your factory when the machine is installed, as well as detailed manuals and video tutorials. Remote support is also available. -
Q: How long is the warranty period?
A: Our standard warranty is 12 months from the date of shipment or 18 months from the date of installation, whichever comes first. Extended warranty plans can be arranged. -
Q: Can the machine be adapted for other polymers like PP or PVC?
A: The standard design is optimized for HDPE. However, with modifications to the extruder and cooling system, it can process PP as well. PVC requires a twin-screw extruder and different winding head material; please consult our engineers. -
Q: What is the minimum order quantity (MOQ)?
A: For standard models, the MOQ is 1 set. Custom designs may require a minimum of 1 set as well. We welcome trial orders. -
Q: How do you ensure the machine meets CE or other international standards?
A: While we hold ISO certifications, the machine can be manufactured to comply with CE, UL, or other standards upon request. Please specify your target market during inquiry.
