As a leading manufacturer with over a decade of expertise in plastic machinery, Qingdao Yongke Machinery Co., Ltd. proudly presents our advanced HDPE Plastic Spiral Hollow Wall Winding Pipe Extrusion Line. Engineered specifically for the production of high-quality pipes used in water storage tanks, this production line represents the culmination of our commitment to innovation, reliability, and efficiency. Our facility, spanning 10,000-30,000 square meters, is dedicated to crafting machinery that meets the rigorous demands of global markets, from North America and Europe to Southeast Asia and Africa. This extrusion line is designed to empower manufacturers to produce durable, leak-proof, and cost-effective piping solutions that are essential for modern water management infrastructure.
This fully integrated production system transforms HDPE raw material into robust spiral wound pipes with a hollow wall structure. The unique design of the pipe provides an excellent strength-to-weight ratio, making it ideal for large-diameter applications in water storage tanks, sewage systems, and industrial fluid transport. The line's precision engineering ensures consistent wall thickness, smooth interior surfaces, and strong inter-layer fusion, resulting in pipes that offer superior hydraulic performance and long-term structural integrity.
Core Technical Features & Operational Advantages:
- High-Efficiency Extrusion: The heart of the line features a robust, computer-controlled extruder with optimized screw design for stable and homogeneous melting of HDPE granules, ensuring consistent material flow and high output rates.
- Precision Winding & Fusion: The automated winding unit precisely layers the extruded HDPE strip in a continuous spiral pattern. Integrated heating and pressure systems create a permanent, monolithic fusion between layers, eliminating the need for adhesives and guaranteeing joint strength equal to the pipe wall.
- Hollow Wall Structure Formation: A key innovation is the integrated corrugator that forms the hollow chambers within the pipe wall during the winding process. This structure significantly enhances the pipe's ring stiffness and resistance to external loads while minimizing material usage and overall weight.
- Intelligent Control System: A centralized PLC with a user-friendly touchscreen HMI allows for precise control over all process parameters—temperature, speed, winding pitch, and cooling. Recipe storage enables quick changeovers between different pipe specifications.
- Automated Cutting & Handling: The downstream section includes an automatic traveling saw for clean, burr-free cutting to pre-set lengths. A stacking or conveying system then organizes the finished pipes for packaging, reducing manual labor and improving safety.
Key Specifications & Performance Data:
| Parameter | Specification / Capability |
|---|---|

The benefits for our clients are substantial. By investing in this extrusion line, water tank manufacturers can achieve significant material savings due to the efficient hollow-wall design without compromising strength. The high degree of automation lowers labor costs and minimizes human error, leading to consistent product quality. The pipes produced are highly corrosion-resistant, have a smooth inner wall for optimal flow, and possess excellent weathering and chemical resistance, ensuring a long service life for the final water storage application. Furthermore, the production process is environmentally friendly, with minimal waste generation.
Frequently Asked Questions (FAQ):
Q1: What is the main advantage of a spiral hollow wall pipe compared to a solid wall pipe for water tanks?
A: The hollow wall structure provides exceptional ring stiffness and resistance to external soil pressure and loads, while using less raw material. This results in a lighter, more cost-effective pipe that maintains high structural performance, ideal for buried or large-diameter tank applications.
Q2: Can this line process recycled HDPE material?
A: The line is primarily designed for virgin HDPE to ensure the highest quality and pressure ratings for potable water storage. The use of a certain percentage of high-quality recycled material can be discussed and tested based on the final pipe specification requirements.
Q3: How is the pipe length controlled, and what are the standard lengths produced?
A: Pipe length is precisely controlled by the PLC. The automatic cutting saw travels with the pipe and cuts at the programmed length. Standard lengths are often 6 or 12 meters, but the system can be customized to produce any specific length required by the client.
Q4: What is the typical lead time for delivery and installation of such a production line?
A> Lead time depends on the specific configuration and customization. Generally, for a standard model, delivery takes 60-90 days after order confirmation. We provide detailed installation manuals and can dispatch engineers for on-site installation guidance and commissioning.
Q5: What kind of after-sales support and training do you provide?
A> We offer comprehensive support including remote technical assistance, a supply of spare parts, and operational & maintenance training for your technicians. Our service team is committed to ensuring the line runs smoothly throughout its lifecycle.
Q6: Is the production line energy-efficient?
A> Yes, the line incorporates several energy-saving features. These include high-efficiency AC variable frequency drives for motors, insulated heating barrels with precise PID control to minimize heat loss, and an optimized cooling system design.
Q7: Can the line produce pipes with different colors for identification purposes?
A> Absolutely. By using HDPE granules of the desired color (commonly black, blue, or orange for different applications), the line can produce pipes in various colors. Color masterbatch dosing systems can also be integrated.
Backed by our ISO9001, ISO14000, and OHSAS18001 certifications, every machine from Qingdao Yongke Machinery is built to international standards of quality, environmental management, and occupational safety.
