PE Series Vacuum Calibration Line for Pre-Insulated HDPE Casing Pipe with 110-2200mm Specification and Rigid Polyurethane Foam Insulation

The PE-Vacuum Calibration Insulation Pipe Production Line is advanced machinery designed for manufacturing pre-insulated pipes used in energy-saving trenchless pipeline installations. These pipes feature rigid polyurethane foam (PUF) insulation within a protective outer casing, making them ideal for heating networks with a working pressure of 1.6 MPa and water temperatures up to 403°K (130°C), with short-term tolerance up to 423°K (150°C).

• Steel pipe range: 60mm-2000mm
• Used materials: ISO (isocyanate), POLY (premixed polyether polyols), PE
