| Product List |
The PE Series Pre-Insulated Pipe Extrusion Line is designed by
absorbing advanced tube extrusion technology from Germany and
improved by Qingdao Huashida Machinery Co., Ltd. This production
line features an integrated design that includes extrusion, vacuum
calibrating, cooling, pulling, cutting, and stacking, delivering
excellent performance in automatic operation, extrusion capacity,
stability, and service life.
Advantages of Vacuum Calibration
Compared to traditional internal pressure methods, the vacuum
calibrating method offers superior stiffness, pressure resistance,
and surface smoothness, making it the most advanced and popular
technology for pre-insulated pipe production globally.
PE-Vacuum Calibration Insulation Pipe Production Line
The vacuum calibrating method is particularly suited for producing
pre-insulated pipes with an outer casing. This technology is
increasingly used in domestic construction, emphasizing
energy-saving trenchless pipeline installation. The pipes and
fittings are insulated with rigid polyurethane foam (PUF
insulation) encased in a protective shell.
Working Pressure: Up to 1.6 MPa
Water Temperature: Up to 403 K (130 °C), with short-term increases
up to 423 K (150 °C)
Structure
The PUF insulation system consists of a rigid "pipe-in-pipe"
structure, which includes:
Carrier Pipe: Made of steel or galvanized steel
Insulation Layer: Rigid polyurethane foam
Outer Jacket: High-density polyethylene for underground
installation or galvanized steel for above-ground use
Rigidity and Performance
The rigidity of the system is enhanced by strong connections
between the steel pipe, polyurethane insulation, and jacket pipe.
The pre-shot blast or blast cleaning of the steel pipe surface
optimizes the performance of the polyurethane insulation and the
corona surface of the polyethylene shell.

Increased Reliability: The PUF insulation system significantly enhances the reliability
of the pipeline.
Remote Condition Monitoring: Enables operational availability and monitoring of the PUF
insulation, allowing for early detection and repair of coolant
leaks, thus preventing typical accidents associated with thermal
networks of other designs.
This PE Series Pre-Insulated Pipe Extrusion Line represents a
cutting-edge solution for energy-efficient pipeline systems,
suitable for various applications in heating networks and beyond.
