PE-Vacuum Calibration Insulation Pipe Production Line
This advanced machinery is widely recognized for producing
pre-insulated pipes used in energy-saving trenchless pipeline
installations. These pipes feature rigid polyurethane foam (PUF)
insulation within a protective outer casing, ideal for heating
networks with a working pressure of 1.6 MPa and water temperatures
up to 403°K (130°C), with short-term tolerance up to 423°K (150°C).
The "pipe-in-pipe" structure consists of:
Carrier Pipe: Steel or galvanized steel.
Insulation Layer: Polyurethane foam (PUF).
Outer Casing: High-density polyethylene (HDPE) for underground installations or
galvanized steel for above-ground applications.
Advantage
Enhanced Reliability: The PUF insulation system ensures durability and operational
efficiency.
Remote Monitoring: Integrated condition monitoring allows early detection and repair
of coolant leaks, preventing accidents common in other thermal
network designs.
Energy Efficiency: Optimized for trenchless laying, reducing installation costs and
environmental impact.
High Performance: Superior stiffness, pressure resistance, and surface quality due
to vacuum calibration technology.
