Product Specification
Product Description
Product Description
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 PLC intelligent control, and ensures high-speed, energy-efficient, and environmentally friendly performance - helping customers save production costs.
Structure of Pre-Insulated Pipe:
Carrier Pipe: Steel / Stainless Steel / Plastic / Copper
Insulation Layer: Polyurethane Rigid Foam (PU)
Outer Jacket: High-Density Polyethylene (HDPE) Protective Shell
Detailed Photos
