A Pipeline Jacket Casing Production Line for Steel Pipes is an advanced industrial system designed to produce protective outer casings (jackets) that surround steel pipelines, enhancing their durability, insulation, and resistance to environmental damage. This production line is widely used in industries such as oil & gas, district heating, water supply, and chemical transport. It manufactures high-quality outer layers—typically made from HDPE (High-Density Polyethylene) or similar thermoplastic materials—that act as a shield for steel pipes against corrosion, moisture, and mechanical impact.

• High Automation: PLC-control systems ensure consistent quality and reduced labor
• Precision Engineering: Uniform thickness and diameter for reliable pipe protection
• Energy Efficient: Optimized heating and cooling systems reduce energy consumption
• Customizable Design: Suitable for different pipe diameters and coating requirements

1. Raw Material Feeding: Plastic granules (usually HDPE) are loaded into the system
2. Extrusion System: The material is melted and extruded through a die to form a continuous plastic pipe or casing
3. Vacuum Calibration & Cooling: The extruded casing is shaped and cooled to achieve accurate dimensions and smooth surface finish
4. Haul-Off Unit: The casing is continuously pulled at a controlled speed
5. Cutting or Winding System: Finished casings are cut into required lengths or coiled for storage and transport
