High Reliable PU Foaming Injection Pipe HDPE Jacket Extrusion Line
Product Description
HDPE jacket pipe extrusion line is high-efficiency equipment with high speed and energy saving for producing HDPE pipe used as protective cover of PU foam thermal Pre-insulated Pipe according to international standard.
The HDPE jacket pipe is produced by vacuum calibrating method with smooth internal and external wall, long service life, good anti-corrosion insulation and mechanical performance.
HDPE Jacket Process Flow: A Seamless Journey from Raw Material to Final Product
The seamless process begins with vacuum feeding PE granules, followed by hot air drying to ensure material purity. Next, the extrusion plasticizing stage transforms the material, which is then expertly mold-shaped. Vacuum sizing ensures precision, water cooling solidifies, and the product is carefully pulled out. Finally, it is skillfully cut into pipes, ready for carrier laying-off.
