Spraying Winding Prefabricated Directly Buried Insulating Pipe Production Line

Equipment Composition

Steel pipe transmission system, surface treatment system, steel pipe heating system, polyurethane spraying system, PE extrusion winding system, water cooling system, pipe end cutting machine grinding system, hydraulic and pneumatic system, detection system and electric control system.

Equipment Characteristics

• Equipped with medium-frequency heating system to improve the foaming quality of "black and white" materials;
• The metering pump of the feeding system delivers material with precise metering and good foam density;
• After spraying and foaming, there is no swelling stress, which can reduce the thickness of the polyethylene outer protective layer;
• The thickness of foam and polyethylene outer protective layer can be adjusted according to needs;
• Electric adjustment of the distance and angle of the conveyor wheel;
• Online continuous production, smooth operation of the production line, and high processing efficiency.
