A Seamless Journey from Raw Material to Final Product:
The 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 the form, and the product is carefully pulled out. Finally, it is skillfully cut into pipes, ready for carrier laying-off.
Streamlined Step-by-Step Precision:
Steel Pipe Pretreatment: Meticulous surface preparation of the steel carrier pipes.
HDPE Outer Pipe Crafting: Creation of the robust HDPE outer protective jacket.
Insulation Layer Creation: The steel pipe is inserted into the HDPE casing with strategic supports. Both ends are sealed with flanges, and the assembly is moved to the foaming platform.
Injection & Curing: A high-pressure foaming machine injects polyurethane material. After curing, seals are removed, culminating the masterful production process.
