PU Foam HDPE Jacket Pipe Extrusion Line Plastic Extruder

The polyurethane pre-insulated piping system produced with a vacuum calibration process is designed for superior thermal performance and long-term reliability.
This system is composed of three main layers: an inner steel pipe, a polyurethane (PU) foam insulation layer, and a high-strength HDPE protective outer jacket. Pipe diameter range: 110-2200mm

Core Advantages:
Vacuum Calibration Process:
Guarantees high dimensional accuracy and stable forming quality.
Surface Quality:
Achieves smooth inner and outer surfaces, contributing to reduced friction and better insulation performance.
Long-Term Durability:
Exhibits excellent resistance to corrosion, moisture, and mechanical stress, extending service life.
Robust Mechanical Properties:
Designed to withstand harsh operating conditions and maintain structural integrity.


Application Scope:
Suitable for various temperature-controlled pipeline projects, including:
District heating and cooling networks
Hot and chilled water distribution
Oil and gas transmission pipelines
Industrial high-/low-temperature process lines

• High Efficiency: High-speed extrusion and energy-saving design.
• Automatic Control: PLC-integrated systems for real-time monitoring and easy operation.
• Superior Quality: Produces pipes with smooth walls, excellent mechanical strength, and anti-corrosion properties.
• Wide Application: Ideal for protecting PU foam insulation in hot/cold water, central heating, chemical, and oil pipelines.
• Customization: Available in various models to handle different pipe diameters and capacities (e.g., 110mm to 2000mm).
