Heat Insulation Pipe Line

The Heat Insulation Pipe Line produced by JWELL has a unique and novel design. It adopts a high-efficiency single-screw extruder and is manufactured by introducing advanced foreign technology. The Siemens PLC processor ensures stable and reliable operation of the equipment.

Heat Insulation Pipe Line Process composition


Steel Pipe Derusting-PU Painting-Online Monitoring-PE Wrapping-Spray Cooling-Track Cutting-Product Inspection-Product Storage


  • Heat insulation pipe line full line steel pipe online reliable
  • The overall spraying uniformly reduces the water absorption rate of the insulation layer
  • The wall thickness of the adjustable sheet can save the cost of the product, realize continuous production and improve the production efficiency
  • The output of the winding method improves the mechanical properties of the outer protective tube
  • Improve the closed cell rate of the insulation layer, reduce the thermal conductivity of the insulation layer, and reduce energy consumption

High-frequency steel pipe preheating+polyurethane spraying

  • Reduces the axial eccentricity of the thermal insulation pipe, no need to make another outer protective pipe, and can be quickly switched between different  specifications
  • The leakage alarm line can be pre-buried to automatically detect the leakage fault of the pipe network, accurately indicate the fault location, and automatically alarm
  • The heat insulation pipe line adopts the “spraying + winding” process to produce prefabricated direct-buried insulation pipes. The thickness of the polyurethane insulation layer and the polyethylene outer sheath can be adjusted arbitrarily according to the needs
  • The production process does not need to increase the input of the corresponding mold tooling, which is simple and easy to operate.
  • Because the process of “spraying and winding prefabricated directly buried thermal insulation pipe” does not generate expansion pressure on the polyethylene outer sheath during foaming, the thickness of the polyethylene outer sheath can be made relatively thin, which saves the cost of raw materials when it is suitable for use.
