The PE Series Pre-Insulated Pipe Extrusion Line, developed by Qingdao Huashida Machinery Co., Ltd., adopts advanced German extrusion technology and integrates extrusion, vacuum calibration, cooling, hauling, cutting, and stacking into a fully automated system.
This production line features high output, stable performance, excellent product quality, and long service life, making it ideal for manufacturing HDPE outer casing pipes.
Compared with traditional internal pressure calibration, the vacuum calibration method provides:
1 Higher pipe stiffness
2 Better pressure resistance
3 Smoother pipe surface
It is one of the most advanced and widely used technologies in the industry.
This extrusion line is specially designed for producing HDPE outer casing pipes used in PUF (polyurethane foam) pre-insulated pipelines, widely applied in:
1 District heating systems
2 Energy-saving pipeline networks
3 Trenchless pipeline installation
1 Inner Pipe: Steel or galvanized steel
2 Insulation Layer: Polyurethane foam (PUF)
3 Outer Jacket:
3.1 HDPE for underground installation
3.2 Galvanized steel sheet for above-ground installation
