| High Light | PE series pre-insulated pipe extrusion line ，vacuum calibration pipe production line ，pre-insulated pipe extrusion machine with warranty | ||
The PE series pre-insulated pipe extrusion line, designed by Qingdao Huashida Machinery Co., Ltd. with advanced German extrusion technology, features an integrated system for extrusion, vacuum calibration, cooling, pulling, cutting, and stacking. It delivers high automation, large extrusion capacity, stable performance, and long service life.
Compared with internal pressure calibration methods, the vacuum calibration method offers superior pipe stiffness, pressure resistance, and surface smoothness, making it the most advanced and popular technology in the world.
This production line is specially designed for manufacturing the outer HDPE casing pipes used in PUF (polyurethane foam) pre-insulated pipelines, widely applied in energy-saving heating networks and trenchless pipeline laying.
Working pressure: up to 1.6 MPa
Water temperature: up to 130 °C (403 K)
Short-term temperature peak: 150 °C (423 K)
Pipe Structure (Pipe-in-Pipe Design)
Inner carrier pipe: Steel or galvanized steel
Middle layer: Polyurethane foam thermal insulation
Outer jacket pipe: High-density polyethylene (HDPE) for underground installation or galvanized steel sheet for above-ground installation
