HDPE Pre-insulated Pipe Casing Extrusion Line
I. Product Introduction
The HDPE pre-insulated pipe casing extrusion line is a highly efficient and energy-saving device used for manufacturing HDPE pipes that serve as protective covers for polyurethane (PU) foam thermal pre-insulated pipes in accordance with international standards. The HDPE casing pipes produced by this line are made using the vacuum calibrating method, which ensures smooth internal and external walls, long service life, excellent anti-corrosion insulation, and good mechanical performance.
