HDPE Thermal Pre-Insulated Pipe Outer Jacket Casing Extrusion Machine Production Line for PU Foam

The PE Casing Pipe Extrusion Production Line is a high-efficiency, high-speed, and energy-saving solution designed to manufacture PE outer jacket pipes for PU foam pre-insulated pipes in accordance with international standards.

The production line adopts advanced vacuum calibration technology instead of the traditional internal inflation method, ensuring uniform wall thickness and smooth inner and outer surfaces. The finished pipes offer excellent corrosion resistance, reliable mechanical performance, and long-term durability, making them ideal for protecting PU foam insulation in district heating and other thermal insulation pipeline systems.

• District Heating Systems: Used as the outer protective casing for pre-insulated pipes in urban and industrial heating networks.
• Underground Heat Supply Pipelines: Protects PU foam insulation from moisture, soil corrosion, and external mechanical damage.
• Central Heating Networks: Suitable for long-distance hot water transmission and centralized heating infrastructure.
• Industrial Thermal Pipelines: Applied in factories, power plants, and industrial facilities for transporting hot water and other thermal media.
• Oil and Gas Pipeline Insulation: Provides an outer protective layer for insulated pipeline systems.
• Municipal Infrastructure Projects: Suitable for underground thermal pipeline construction, energy-saving renovation, and urban utility networks.
• Pre-Insulated Pipe Manufacturing: Used by pipe manufacturers to produce HDPE/PE outer jackets for PU foam insulated steel pipes and plastic pipes.

• Compact Design: Space-saving structure for convenient installation and factory layout.
• High Automation: Easy to operate, with only one operator required, helping reduce labor costs.
• Long Service Life: Robust construction and reliable components ensure durable, long-term operation.
• High Production Efficiency: High-performance extruder delivers high output and stable operation.
• Uniform Pipe Quality: Produces pipes with consistent wall thickness and smooth inner and outer surfaces.
• Material Saving: Precise extrusion control minimizes raw material waste and improves material utilization.
• One-Step Forming: Integrated production process eliminates the need for edge trimming, improving efficiency and reducing waste.
• Wide Production Range: Suitable for PE casing pipes with diameters ranging from 110 mm to 2000 mm, depending on the model.
