High Output Energy Saving Customizable HDPE Pipe Extrusion Line for Pre-Insulated Pipe Production

The HDPE jacket pipe extrusion line is designed for extruding a thin-wall outer protective shell used in Polyurethane (PU) foaming pre-insulated directly buried pipes.

This shell provides mechanical protection and waterproofing for the insulation layer.

Huashida Company, a leading manufacturer in China, adopts the vacuum calibration method for stable and precise production. The line operates smoothly, features Siemens PLC intelligent control, and ensures high-speed, energy-efficient, and environmentally friendly performance - helping customers save production costs.
