Product Description

Our fully automated production line is specially designed for manufacturing polyurethane (PU) foam insulated pipes with diameters ranging from Φ48-630mm. By integrating multiple processes including outer protective pipe extrusion and insulation material pouring into one continuous operation, this system ensures high production efficiency while maintaining consistent product quality. The equipment guarantees perfect bonding between the inner pipe, insulation layer, and outer protective jacket, making it ideal for various insulated pipeline applications.

Fully automated continuous production process
High efficiency with stable product quality
Precise foam density control for optimal insulation
Dual protection: epoxy anti-corrosion coating + HDPE outer jacket
Accommodates multiple pipe diameters from Φ48-325mm
