Qingdao Yongke Machinery Co., Ltd. proudly introduces our advanced HDPE Inspection Manhole Making Machine and Polyethylene Spiral Wound Tank Pipe Extrusion Line. With over a decade of engineering excellence since 2010, we specialize in manufacturing robust, high-efficiency extrusion lines for the production of large-diameter spiral wound pipes, tanks, and manholes. This integrated solution enables manufacturers to produce inspection manholes and spiral wound tank pipes in a continuous, automated process, significantly reducing production costs while ensuring superior product quality. Our machinery is designed to meet the rigorous demands of infrastructure, municipal drainage, and industrial storage applications.
Our extrusion line combines a powerful HDPE single-screw extruder with a precision spiral winding system, delivering consistent melt flow and uniform wall thickness. The machine is capable of processing virgin HDPE, PE100, and recycled materials, offering flexibility for various project requirements. With a PLC-based control system and user-friendly touch screen interface, operators can easily monitor and adjust parameters such as temperature, screw speed, and winding tension, ensuring optimal production efficiency.
Key Features & Technical Specifications
- High Output Capacity: Production rates from 100 kg/h to 500 kg/h, depending on model and product size.
- Versatile Product Range: Produces spiral wound manholes (diameter 400mm-2500mm) and tank pipes (diameter 300mm-3000mm) with customizable lengths.
- Energy-Efficient Design: Equipped with variable frequency drives (VFD) and energy-saving heating zones, reducing power consumption by up to 20% compared to traditional lines.
- Robust Construction: Heavy-duty steel frame, hardened gearbox, and wear-resistant barrel/screw made of 38CrMoAlA alloy with nitriding treatment.
- Advanced Control System: Siemens PLC with HMI touch screen; automatic fault diagnosis and alarm functions.

Frequently Asked Questions
Q1: What raw materials can this machine process?
A: It can process HDPE (PE100, PE80), PP, and recycled polyethylene pellets. For recycled materials, pre-processing like washing and drying is recommended.
Q2: What is the typical production output for manhole making?
A: For a manhole of 1000mm diameter and 1.5m length, the cycle time is about 10-15 minutes per piece, depending on wall thickness and cooling efficiency.
Q3: Can I produce different diameters on the same machine?
A: Yes, with quick-change molds. We offer mold sets for diameters from 400mm to 2500mm. Changeover takes approximately 30-60 minutes.
Q4: What is the power consumption of the line?
A: For a standard model (100-250 kg/h), total installed power is around 150-200 kW. Actual consumption depends on material and output.
Q5: Do you provide installation and training?
A: Yes, we send engineers to supervise installation and provide 3-5 days on-site training for your operators. Remote support is also available.
Q6: What is the warranty period?
A: We offer a 12-month warranty for the whole machine (excluding consumables like screws and barrels). Extended warranty plans are available.
Q7: Can the line produce both manholes and spiral wound pipes?
A: Absolutely. By adjusting the mandrel and winding parameters, the same line can produce both products. A switch takes about 2 hours.
Q8: What certifications does the machine comply with?
A: Our machinery is designed to meet ISO standards and CE requirements. Specific certifications like UL or GOST can be arranged per your request.
