Pre Insulated Steel Pipe Plastic HDPE PE Jacket Casing Shell Pipe Extrusion Line
PE Shell Pipe Extrusion Line is high-efficient with high speed and energy saving for producing HDPE thin wall pipe, which is used as a protective cover of PU foam thermal Pre-insulated Pipe according to international standards.
The HDPE jacket pipe is produced by vacuum calibrating method with smooth internal and external walls, long service life, good anti-corrosion insulation and mechanical performance.
Features of HDPE jacket pipe extrusion line
-small space required
-high degree of automation, can be operated by 1-2 people, saving labor costs.
-long service life.
-high-efficiency extruder gives larger output and stable performance.
-pipe wall is uniform and smooth
-no waste of raw material
-once forming. No need to trim the edge.
-Dust-free cutting

Main machine- High-efficiency single screw extruder
The screw is with barrier & mixing head; the barrel is a new model with slotting (channel). Both guarantee good jellification, large output and stable performance of the extruder.
The straight cylinder section of the pipe die makes the pipe wall smooth and uniform;
Calibrators
Dust-free planetary cutting machine
It adopts the blade punching principle to realize no-dust cutting. It is mainly composed of the cutting device, the clamping device, the synchronous movement device and the frame.
Controlling system
The complete line is controlled by PLC, with a good human-machine interface, all technical parameters could be set and indicated by touching the screen. The controlling system is designed according to the customer's requirements.
