PLC Controlled HDPE Jacket Pipe Extrusion Line for District Heating Pre-insulated Pipes
The HDPE Jacket Casing Pipe Extrusion Line is a high-performance system engineered to produce durable protective casings for PUR (Polyurethane) foam pre-insulated pipes. Utilizing state-of-the-art vacuum calibration technology, this production line ensures that casing pipes meet rigorous international standards for thermal insulation and mechanical protection.
By integrating seamlessly into the (HDPE casing + PU foam) manufacturing workflow, our equipment delivers high-speed output while maintaining energy efficiency. The resulting pipes feature superior anti-corrosion properties and high-precision diameter accuracy, essential for long-term underground and industrial service.
Primary Applications:
District Heating Systems: Core protection for urban thermal networks.
Industrial Transmission: Safe transport of hot/chilled water and chemicals.
Energy Infrastructure: Reliable casing for gas and oil pipeline networks.
Geothermal Projects: Specialized protection for geothermal heating loops.

Note: Custom modifications are available. We can calibrate motor power and screw designs to meet your specific resin requirements.
The line utilizes a fully automated, synchronized process to ensure a "one-time forming" result, eliminating the need for secondary edge trimming.
Material Prep: Vacuum Loader & Hopper Dryer for moisture-free granules.
Extrusion: High-efficiency Single Screw Extruder for stable plasticizing.
Sizing: Vacuum Calibration Table for precise outer diameter control.
Cooling: Multi-stage Water Spraying Tanks for rapid heat dissipation.
Finishing: Heavy-duty Hauling Machine & Precision No-Dust Cutting System.
HDPE Jacket Production Process Flow
The production process is fully automated, simple to operate, and efficient, with the following steps:
Feeding → Drying → Plasticizing → Mold Shaping → Vacuum Sizing → Cooling → Hauling → Cutting → Final Discharge.
Optimized Footprint: Compact design allows for flexible installation in various workshop layouts.
One-Man Operation: High-level automation reduces labor overhead while maintaining consistency.
Precision Engineering: Ensures uniform wall thickness and smooth internal/external surfaces to prevent PU foam leakage during the injection phase.
Sustainability: High raw material utilization with zero-waste trimming processes.
Proven Track Record: Over 380 production lines operational across Russia, Kazakhstan, Iran, and Nigeria.
Engineering Depth: Backed by 9 senior engineers specializing in pipeline anti-corrosion and HDPE extrusion.
