Pre-Insulated Pipe Production Line with HDPE Jacket and PU Foaming for Customizable Size and Vacuum Cooling in 110-1870 mm Diameter Range
The HDPE jacket pipe extrusion line is specifically designed for manufacturing high-quality HDPE outer casing pipes used in pre-insulated pipe systems. It ensures stable, efficient production with excellent output and easy operation.
This equipment is widely applied in pipeline insulation production lines, supporting customizable configurations to meet different pipe diameter and production requirements.
The final insulated pipe consists of three layers:
-
Steel pipe (inner carrier)
-
Polyurethane (PU) foam (insulation layer)
-
HDPE jacket pipe (outer protective casing)
The finished pipe features high strength, good toughness, smooth surface, uniform wall thickness, and strong pressure resistance.
Pre-insulated pipes produced by this line are widely used in:
-
Liquid and gas transmission networks
-
Chemical pipeline insulation
-
Oil and chemical industries
-
Centralized heating networks
-
Municipal engineering
High-temperature prefabricated directly buried insulation pipes offer:
-
Excellent thermal insulation performance
-
High safety and reliability
-
Reduced project cost
This plastic pipe production line is mainly composed of 9 parts:
- Auto Vacuum feeder :
- Hopper dryer
- Efficient single screw extruder
- Mould
- Vacuum calibration tank
- Hauling machine
- Cutting machine
- Stacker
- PLC central control system
The machines inclued in the production line can also be customed as your specific requirements.
