HDPE Plastic Jacket Pipe Pre-Insulated Pipe Casing Extrusion Line
HDPE Pre-Insulated Pipe Production Line (Vacuum Calibration Type)
This high-efficiency production line is designed for manufacturing HDPE jacket pipes used as the outer casing of PU foam pre-insulated pipes. These pipes are widely used in district heating, oil, natural gas, and other industrial applications requiring thermal insulation.
Adopting German extrusion technology and vacuum calibration method, the production line ensures excellent pipe stiffness, pressure resistance, and surface smoothness.
Inner Pipe: Steel or galvanized steel (for transporting hot water, steam, etc.)
Middle Layer: PU foam insulation (for heat preservation)
Outer Casing: HDPE pipe (produced by this line)
Auto Vacuum Feeder
Hopper Dryer
High-Efficiency Single Screw Extruder
Mold with Copper Calibrating Sleeve
Vacuum Calibration Tank
Haul-Off Machine
No-Dust Cutting Machine
Pipe Stacker
PLC Central Control System
Main Extruder
Structural features: high strength, wear resistance, corrosion resistance, good screw plasticization effect; The temperature control system adopts ceramic heating coils for heating and fan cooling, and uses temperature sensors, temperature controllers, etc. for automatic temperature control.
Control system
Adopting Siemens PLC centralized control and unique DCL software design. Implemented interoperability between systems, windows, and human-machine interfaces, endowing machines with AI intelligence and simple operation. Save labor and effort, with no safety hazards
Planetary cutting machine
By using the Haff block planetary cutting machine, it can ensure that the cutting section is vertical and neat, without the need for secondary processing. Adding a powder collection system can ensure a clean and tidy production site.
High Efficiency: Output up to 1250kg/h
Pipe Diameter Range: Φ110mm - Φ1860mm
Fully Automated: PLC control, touchscreen operation
One-Time Forming: No need for edge trimming
Customizable: Machine configuration adjustable per customer needs
Energy Saving: Low scrap rate (only 0.5m at pipe joints)
Durable Equipment: Thick vacuum box, service life over 5 years
High Precision: Planetary cutter with automatic length measurement and dust-free cutting
