As a leading manufacturer with over a decade of experience, Qingdao Yongke Machinery Co., Ltd. specializes in providing robust and efficient plastic extrusion solutions. Our High Quality HDPE Hollow Wall Spiral Pipe Extrusion Machinery is engineered for high-volume, stable production of durable pipes essential for modern infrastructure. Operating from our expansive 10,000-30,000 square meter facility, we combine advanced technology with stringent quality control to deliver machinery that enhances your production capability and profitability. This machine is a cornerstone for businesses looking to produce reliable drainage, sewerage, and conduit pipes with superior structural integrity and cost-effectiveness.
This extrusion line is designed for maximum efficiency and output consistency. It transforms high-density polyethylene (HDPE) granules into strong, lightweight hollow-wall spiral pipes with a smooth interior and corrugated exterior. The spiral design, created by a continuous winding and welding process, provides exceptional ring stiffness and resistance to external loads, making the final pipes ideal for buried applications.
- High-Efficiency Extruder: Features a high-speed, high-torque screw and barrel designed for optimal plasticizing and mixing of HDPE material. The precision temperature control zones ensure consistent melt quality, which is critical for achieving uniform pipe wall thickness and strong weld seams.
- Advanced Spiral Forming Unit: The core of the machine where the molten HDPE is extruded through a specially designed die head to form a continuous spiral profile. The unit includes precise speed and tension controls to ensure perfect overlap and fusion of the spiral ribs, creating the hollow wall structure.
- Intelligent Control System: A user-friendly PLC with a color touch-screen HMI allows for centralized control of all parameters. Operators can easily set and monitor temperatures, screw speeds, haul-off speeds, and winding tension, ensuring repeatable production and quick changeovers between different pipe sizes.
- Robust Cooling and Haul-Off: A multi-stage water cooling tank rapidly sets the pipe shape, while a caterpillar haul-off unit provides steady, synchronized pulling force. This combination guarantees precise pipe dimensions and prevents deformation.
- Energy-Saving Design: The machine incorporates frequency inverter drives for major motors and high-efficiency ceramic heating bands, significantly reducing power consumption compared to conventional designs, which lowers your operational costs.
- Durability and Low Maintenance: Built with high-grade steel and premium wear-resistant components in critical areas, the machinery is designed for continuous operation with minimal downtime. Easy access panels and a modular design simplify routine maintenance and servicing.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of producing hollow wall spiral pipes compared to solid wall pipes?
A1: Hollow wall spiral pipes offer a superior strength-to-weight ratio. The spiral corrugated structure provides high ring stiffness and resistance to crushing forces while using less material, making them lighter, more cost-effective to produce and transport, and easier to install.
Q2: Can this machine run recycled HDPE material?
A2: Yes, the machine is designed to process both virgin and certain grades of high-quality recycled HDPE granules. We recommend discussing your specific material blend with our engineers to ensure optimal screw design and process parameters for consistent output.
Q3: How is the pipe diameter changed on this machine?
A3: Changing the pipe diameter typically requires replacing the forming mandrel and adjusting the haul-off speed and winding parameters. Our machines are designed for modularity to facilitate these changes, and we provide detailed operational manuals and training.
Q4: What kind of after-sales support do you provide?
A4: We provide comprehensive support including installation supervision via video call or on-site engineers (optional), detailed operational and maintenance manuals, online technical support, and a supply of readily available spare parts. Our service team is responsive to ensure minimal disruption to your production.
Q5: What is the typical lead time for delivery and installation?
A5: The lead time depends on the machine configuration and current production schedule. Standard models generally have a shorter lead time. We provide a clear production and shipping schedule upon order confirmation. All machines are shipped from the port of Qingdao.
Q6: Are the electrical components from international brands?
A6> We use reputable international brands like Siemens, Mitsubishi, or Schneider for critical components such as PLCs, drives, and electrical switches as standard or upon request. This ensures reliability, ease of maintenance, and global compatibility of spare parts.
Q7: Can the machine be customized for a specific pipe standard (e.g., ASTM, EN)?
A7: Absolutely. We can customize the forming unit and process parameters to produce pipes that meet various international standards such as ASTM F2306, EN 13476, or other regional specifications. Please provide your target standard during the inquiry.
Q8: What utilities are required to operate this extrusion line?
A8: The main requirements are a stable three-phase electrical power supply (voltage as per your country), a clean water source and drainage system for the cooling circuit, and a compressed air supply for certain pneumatic functions. We provide detailed utility specifications with our technical proposal.
