Qingdao Yongke Machinery Co., Ltd., established in 2010, is a professional manufacturer specializing in plastic pipe production machinery. With a factory area of 10,000–30,000 square meters and an annual export value of US$1–1.5 million, we serve clients across North America, South America, Europe, Africa, and Asia. Our HDPE Inner Rib Reinforced Spiral Winding Pipe Machine is engineered to produce high-quality sewer pipes that meet stringent municipal standards. Combining advanced spiral winding technology with robust inner rib reinforcement, this machine delivers pipes with excellent ring stiffness, hydraulic performance, and durability. Whether for stormwater drainage, sewage systems, or industrial effluent, our solution ensures cost-effective production with minimal maintenance.
Key Features & Technical Specifications
- Inner Rib Reinforcement Design: The unique inner rib structure significantly enhances the pipe's ring stiffness (SN ≥ 8 kN/m²) while maintaining light weight, reducing material cost by up to 20% compared to solid-wall pipes.
- High Precision Spiral Winding: Equipped with servo-driven winding heads and automatic tension control, ensuring uniform wall thickness and consistent rib spacing.
- Energy-Efficient Extrusion System: Barrel and screw made of 38CrMoAlA with bimetallic coating, extending service life and reducing energy consumption by 15%.
- PLC Touch Screen Control: Siemens or Mitsubishi control system with real-time monitoring of temperature, pressure, and production speed. Recipe storage for quick changeover between pipe sizes.
- Integrated Cooling & Calibration Unit: Vacuum sizing sleeve with multi-zone spray cooling ensures accurate outer diameter and ovality control (≤ 1% tolerance).
- Flexible Pipe Diameter Range: From 200mm up to 3000mm, adjustable via interchangeable die heads and winding mandrels.
- Low Noise & Safe Operation: Fully enclosed safety guards and noise reduction covers keep workplace noise below 75 dB.

Advantages for Sewer Pipe Production
Our spiral winding technology offers distinct benefits over conventional extrusion methods:
- Material Savings: The inner rib design reduces HDPE usage by 20–30% while maintaining structural integrity.
- Superior Hydraulic Performance: Smooth inner wall with intermittent ribs reduces friction loss and improves flow capacity.
- Long Service Life: Pipes produced are resistant to corrosion, UV, and chemical attack, with expected lifespan exceeding 50 years.
- Easy Installation: Lightweight pipes (up to 40% lighter than concrete) reduce handling and transportation costs.
- Versatile Raw Material: Compatible with both virgin HDPE and recycled material (up to 30% blend) without sacrificing quality.
