Computerized Control High-Pressure Air Type Polyurethane Spraying Thermal Winding Polyethylene Production Line with 30-100mm Foaming Thickness

The Continuous Polyurethane Spraying Thermal Winding Polyethylene Equipment Production Line manufactures prefabricated buried insulation pipes constructed from three integral components: a robust working steel pipe, a meticulously sprayed polyurethane insulation layer, and a durable extruded polyethylene outer protective layer.

• 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

• External shot blasting and rust removal operation line
• Chuck type spraying operation line
• Extruder
• Die head
• PU Thermal insulation layer winding production line
• PE wrapping operation line
• PE beveling machine
• Cooling system
