HDPE Spiral Winding Corrugated Sewer Culvert Pipe and Tank Extrusion Manufacturing Machinery
Product Spotlights
Qingdao Yongke Machinery Co., Ltd. has been a pioneering manufacturer of plastic extrusion equipment since 2010. Our HDPE Spiral Winding Corrugated Sewer Culvert Pipe and Tank Extrusion Manufacturing Machinery is designed to produce high-quality spiral wound corrugated pipes and tanks with exceptional strength and durability. This advanced production line integrates extrusion, forming, cooling, and cutting processes into one continuous system, delivering efficiency and reliability for large-scale infrastructure projects. With a factory size of over 10,000 square meters and a dedicated team of 51-100 employees, we ensure every machine meets rigorous quality standards.
Key Features & Technical Specifications
- Proven Spiral Winding Technology: Employs a rotating mandrel and extrusion die to form continuous spiral corrugations, producing pipes with smooth inner bore and high ring stiffness (SN8-SN16 available).
- Wide Diameter Range: Capable of producing pipes from DN200 to DN4000 mm, and tanks up to 6,000 mm in diameter, catering to municipal sewer systems, culverts, and storage applications.
- High Output & Energy Efficiency: Single-screw extruder with optimized screw design (L/D ratio 33:1) ensures high plasticizing capacity and low energy consumption. Output ranges from 200 to 600 kg/h depending on configuration.
- Multi-Layer Co-Extrusion Option: Supports up to 3-layer co-extrusion for barrier properties, color coding, or recycled material core layers, reducing raw material costs without compromising performance.
- Automated Control System: Siemens PLC with 10-inch touch screen enables real-time monitoring of temperature, speed, pressure, and wall thickness. Data logging and remote diagnosis available upon request.
- Robust Cooling & Calibration: Vacuum calibration tank with multi-zone water spray cooling ensures precise dimensions and rapid solidification. Air cooling section further stabilizes pipe structure.
- Versatile Downstream Equipment: Integrated cutting saw, bell/socket belling machine, and automatic stacking conveyors for complete production line. Customized belling for rubber ring joints or welded joints.
- Safety & Environmental Compliance: Equipped with emergency stop, overload protection, and soundproof enclosures. Our machines comply with CE standards (available upon request).

Client Benefits
- Cost Savings: Spiral winding technology reduces material usage by 20-30% compared to solid-wall pipes while achieving same strength. Recycled HDPE can be used for core layers.
- Quick Installation: Lightweight yet strong pipes reduce handling and installation costs. Integral bell couplings eliminate additional joint fittings.
- Long Service Life: HDPE resists corrosion, abrasion, and chemical attack. Expected lifespan over 50 years in underground sewage applications.
- Customization Flexibility: Change forming mandrel to produce different diameters and wall thicknesses. Color, stiffness class (SN4-SN16), and tank size are fully adjustable.
- Turnkey Support: We provide installation supervision, operator training, and spare parts packages. Our after-sales team responds within 24 hours.

Frequently Asked Questions (FAQ)
-
What raw materials can this machine process?
Primarily HDPE (virgin or recycled), but also PP and PVC with minor adjustments. The screw and die design are optimized for HDPE, but we can modify for other thermoplastics. -
What is the typical delivery time?
Standard configuration takes 60-90 days after contract signing. Customized machines may require 90-120 days. We provide a production schedule upon order confirmation. -
Can I produce both pipes and tanks on the same machine?
Yes, the machine is designed for both applications. A change of mandrel and cooling tank setup is needed. The downstream cutting system can handle both round pipes and large-diameter tanks. -
What certifications does the machine have?
Our machines are manufactured under ISO9001 quality system. CE certification can be offered as an option for European markets. We also comply with international safety standards. -
How do you ensure product quality?
Each machine undergoes factory testing with your materials before shipment. We provide test videos and reports. A 12-month warranty covers manufacturing defects. -
What is the minimum order quantity?
We accept single-machine orders. For customized lines (e.g., multi-layer co-extrusion), a minimum order of one set is required. Volume discounts are available. -
Do you provide installation and training?
Yes, our engineer can supervise on-site installation and train your operators for 2-3 weeks. Travel and accommodation costs are borne by the buyer. Remote support is also available. -
Can the machine produce pipes with belled ends?
Yes, an integrated belling machine can be added to form socket-and-spigot joints directly on the pipe end. This reduces secondary processing time.
