  • Steel Skeleton Reinforced Pipe Extrusion Line

Steel Skeleton Reinforced Pipe Extrusion Line

The Steel Skeleton Reinforced Pipe is a high-performance composite pipe designed by embedding a steel framework within a polyethylene (PE) or polypropylene (PP) base material. This advanced structure combines the mechanical strength of steel and the corrosion resistance of plastic, resulting in excellent performance for high-pressure and long-term operation.
Bonzer Plastics Machinery specializes in the development and manufacture of PE steel skeleton reinforced pipe extrusion lines, providing reliable and cost-efficient solutions for global customers.

Product Information

2. Product Structure

The pipe is composed of three main layers:

  • Inner Layer: Smooth PE/PP surface ensuring low fluid resistance and hygienic transport.
  • Middle Layer: Embedded steel wire skeleton or steel mesh reinforcement providing high rigidity and pressure resistance.
  • Outer Layer: Corrosion-resistant polymer material protecting the structure from environmental damage.

3. Technical Specifications

Parameter Typical Range Description
Pipe Diameter 63mm – 1200mm Customizable according to project requirements
Operating Pressure Up to 1.6 MPa Depending on skeleton design
Temperature Range -30°C to +80°C Suitable for various environmental conditions
Material Composition PE / PP with embedded steel High strength and anti-corrosion
Connection Type Electrofusion / Flange / Socket joint Leak-free and reliable connection
Service Life ≥ 50 years Long-term durability and stability

4. Key Advantages

  • Superior Strength & Rigidity: Steel reinforcement prevents deformation under high pressure.
  • Excellent Corrosion Resistance: Suitable for transporting chemical and corrosive fluids.
  • Long Service Life: Resistant to aging, corrosion, and temperature changes.
  • Lightweight Design: Easier handling and installation compared to full-metal pipes.
  • Environmentally Friendly: Made from recyclable, non-toxic materials.
  • Stable Flow Performance: Smooth inner surface ensures high flow efficiency and prevents scaling.
  • Low Maintenance: Minimal need for repairs due to excellent joint performance and stability.

5. Applications by Industry

  • Municipal Infrastructure: Urban water supply, drainage, and sewage systems.
  • Industrial Transport: Conveying petroleum, natural gas, and chemicals.
  • Agricultural Irrigation: High-pressure irrigation and drainage networks.
  • Construction Engineering: Building plumbing, air-conditioning, and fire-fighting systems.
  • Mining & Energy: Transport of slurry, gas, or corrosive fluids in mines and power plants.

6. Production Process

  1. Raw Material Feeding – PE/PP granules and steel wire are automatically fed into the extruder.
  2. Extrusion & Steel Embedding – Steel skeleton is formed and continuously embedded in molten polymer.
  3. Cooling & Shaping – Pipe is cooled through a water channel to ensure precise shape and size.
  4. Cutting & Inspection – Pipes are cut to standard lengths and tested for strength, leakage, and integrity.
  5. Packaging – Pipes are bundled, sealed, and prepared for shipment.

7. Quality Control

Bonzer Plastics Machinery follows a strict ISO 9001 Quality Management System, including:

  • Tensile & Pressure Testing
  • Dimensional Precision Check
  • Leakage & Hydrostatic Testing
  • Thermal Aging and Impact Resistance Evaluation

All pipes undergo full inspection before delivery to ensure consistent product quality.

8. Packaging & Delivery

  • Packaging: Wrapped with PE film or placed in wooden pallets.
  • Delivery Time: 15–25 working days after order confirmation.
  • Export Markets: Europe, Southeast Asia, South America, and the Middle East.
  • Customization: Available for pipe diameter, wall thickness, and reinforcement type.
