High-Efficiency Extruder Pre-Insulated Pipe Extruder with Vacuum Calibration and Planetary Cutting for HDPE Jacket Pipe

The PUF insulated pipe jacket pipe extrusion line is high-efficiency equipment with high speed and energy saving for producing HDPE pipe used as a protective cover of  PU foam thermal Pre-insulated Pipe.
It is small in size, easy to operate with an automatic control system and has a long service life.

---Compared with the inflating method (internal pressure method)
1. For 24 hours of working, it reduces 2-3 workers for each shift.
2. There are fewer waste pipes and materials, no need workers to crush waste material.
3. High-efficiency. Take Diameter 960mm as an example, Output is approximately 60 pcs of 11.6meters pipe, it is a much higher output than that of inflating method.
4. Pipe wall is average and smooth, to reduce waste of raw material, and pipe thickness is adjustable.
5. No need to trim edge, once forming.


---The extrusion line comprise equipment and devices as below,
1set Vacuum loader
1set Hopper dryer
1set High-efficiency single screw extruder
1set 25/25 single screw extruder for mark line
1set Vacuum calibration table
1set Water spraying tank
1set Hauling machine
1set Cutting machine
1set Stacker


I. Pipe Usage
---HDPE jacket pipe is the outer casing of the ready insulated pipe, which is widely used in district heating and cooling, oil and gas, and other industrial areas.

II. Machine Advantages
---High-efficiency extruder gives larger output, stable performance.
For example
SJ90/33---600-700kg/h
SJ120/33---800-900kg/h
SJ150/33---1000-1200kg/h


III. Main machine- High-efficiency single screw extruder
---Single screw is with barrier & mixing head; the barrel is a new model with slotting (channel), Both make the security of good jellification, large output, and stable performance.



IV. Controlling system
The complete line could be 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 requirement, to be with PLC, or without.


V. Electrical system
---ABB frequency converter or EUROTHERM speed controller
---Japan RKC temperature controller
---  AC contactors
