Engineering Project Experience

Over the years, WanFu insulation products have been used in municipal heating networks, HVAC systems, energy facilities, petrochemical systems, industrial parks, infrastructure projects, and thermal pipeline renovation projects.

Pre-insulated Polyurethane Direct-buried Pipes

Desay SVW Midwest Base (Chengdu) Project

A factory-prefabricated polyurethane insulated pipeline system supplied for industrial cooling water transmission in an automotive manufacturing industrial park. The project used DN150-DN500 pre-insulated pipes with a total length of approximately 5,000 meters.

  • Application: Industrial cooling water transmission system
  • Challenge: Prevent condensation and corrosion caused by temperature differences between the pipe interior and exterior
  • Solution: HDPE electrofusion casing for joint sealing and V-shaped welding with airtight testing
  • Result: Reliable insulation joint protection and prevention of moisture ingress

Glass Fiber Reinforced Plastic Jacket PU Insulated Pipes

Longling Health Town Hot Spring Water Project

A long-distance hot spring water transmission project using DN90-DN300 prefabricated insulated pipelines with a total installation length of approximately 70,000 meters.

  • Application: Hot spring water collection and long-distance transmission
  • Challenge: Maintain outlet water temperature above 75℃ from a 90℃ water source
  • Solution: Low thermal conductivity rigid polyurethane insulation with thermal conductivity down to 0.022W
  • Result: Achieved temperature loss control of approximately 0.1℃ per kilometer
  • Additional Protection: 3mm thick FRP outer jacket prevents moisture penetration

Rigid Polyurethane Pipe Shells

Liquid Air SMIC Eastern Bulk Gas Station Project

An industrial gas pipeline insulation project serving SMIC production facilities in Shanghai. The system covers DN32-DN400 pipelines with a total length of approximately 18,000 meters.

  • Application: Multi-gas transmission pipeline insulation
  • Challenge: Different gas temperatures require stable thermal insulation performance
  • Solution: High-performance PU pipe shells with thermal conductivity down to 0.022W
  • Additional Treatment: Polyurethane sealant applied to shell joints to prevent condensation

Pre-insulated Heating Pipeline System

Heze Minsheng Heating Project

A large-scale district heating project in Heze High-tech Zone using DN200-DN1000 hot water transmission pipelines with an approximate length of 100,000 meters.

  • Application: Municipal district heating network
  • Challenge: High underground water levels caused risks of steel pipe corrosion
  • Solution: Heat-sealed welding protection at insulation injection ports
  • Solution: HDPE electrofusion joint casing with V-shaped welding and airtight testing
  • Result: Effective prevention of groundwater infiltration and corrosion
