Description
High-Performance Spray Coated PE Wrapped Insulated Pipe for Municipal Pipelines

Huashida's independently developed pre-insulated pipe production line uses a PUR spray and PE wrapping process to manufacture large-diameter insulated steel pipes (508-1620mm) for district heating, chilled water, and oil & gas pipeline networks. The system integrates three core production sections into one turnkey line: an external pipe shot blasting and derusting line, a polyurethane spray foaming line, and a PE wrap winding production line.

Product Specifications
Steel Pipe Diameter 600-1520mm
Foaming Thickness 30-100mm
HDPE Jacket Thickness 3-10mm
Technical Advantages
  • Enhances the mechanical properties of the outer protective tube
  • Thins the wall of the outer protective tube
  • Lowers the water absorption rate of the insulation layer
  • Increases the closed cell rate of the insulation layer
  • Decreases the eccentricity of the insulation pipe axis
  • Improves the uniformity of the overall insulation layer density
  • Boosts the compressive strength of the insulation layer
  • Reduces the thermal conductivity of the insulation layer, minimizing energy loss
Production Process
Steel pipe External shot blasting → PU foam spraying → PE film wrapping → Water cooling → Cutting down pipeline → Trim end of pipe → Printing mark & loading finished pipe → Sealing end of pipe
