HDPE Jacketed PU Pre-Insulated Pipe Production Line with Fully Automatic Control System

HDPE Jacketed PU Pre-Insulated Pipe Production Line with Fully Automatic Control System

Product Description

High-Speed Automatic Pre-Insulated Pipe Extrusion Production Line for pre-insulated pipe is designed by Qingdao Huashida Machinery Co., LTD. It  absorbs and improves developed HDPE pipe extruding technology. It is mainly composed of working steel pipe, PU insulation layer, plastic outer protective pipe and other parts.

Vacuum-calibrated polyurethane pre-insulated pipes deliver superior thermal insulation and long service life. Featuring a steel carrier pipe, PU insulation layer, and HDPE protective jacket, the system ensures excellent strength, corrosion resistance, and energy efficiency. Produced using advanced vacuum calibration technology, the HDPE jacket pipes offer high dimensional accuracy and consistent quality, making them an ideal choice for district heating and cooling pipeline systems.

The vacuum calibrating and insulation pipe production line is currently the most advanced and popular series of anti-corrosion and insulation vacuum sizing pipe production lines internationally.The "Insulation Pipe Production Line" of Qingdao Huashida Machinery Co., Ltd. has been recognized as a First (Set) Technical Equipment in Shandong Province.
