The HDPE protective casing pipe extrusion system constitutes a high-speed, energy-efficient, and high-output equipment setup. It is designed to manufacture HDPE pipes that serve as protective casings for polyurethane foam pre-insulated thermal pipelines, complying rigorously with global standards.
The HDPE jacket pipes are produced through the vacuum calibrating method. This production process ensures that the pipe have smooth internal and external surfaces, an extended service life, excellent Anticorrosion, insulation properties, and reliable mechanical performance.

Production range: pipe dia. 90-2000mm, wall thickness 2.2-20mm
