Steel Pipe Polyurethane Spray Foam Coating Insulated Steel Pipe Production Line

Product Description

Pipe diameter range: 500-1600MM
polyurethane spraying polyethylene winding prefabricated direct buried insulation pipe is composed of working steel pipe for conveying medium, sprayed polyurethane rigid foam insulation layer and winding polyethylene outer casing.

Main features of the production line:
Three-stage dust removal meets environmental standards.
Suitable for continuous production of large-diameter insulated pipes, offering high efficiency and energy conservation.
The production line operates automatically, with automatic loading and unloading of pipes.
Continuous spraying provides consistent coating thickness, conserving raw materials.
Extrusion is performed using a highly efficient and energy-saving extruder. Automated precision machining of pipe joints.

Pipe Usage
