Rigid PPU pipe-in-pipe Pre-Insulated Pipe Production line



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




Production line composition:
-1set Vacuum loader
-1set Hopper dryer
-1set High-effeciency single screw extruder
-1set Vacuum calibration table
-1set Water spraying tank
-1set Hauling machine
-1set Cutting machine
-1set Stacker




---Pipe Usage: out case of thermal insulating pipe, which is widely used in central heating, oil, nature gas and other industrial area.
---Pipe/jacket diameter range: 110-1680mm



Machine Advantages
---High-efficiency extruder gives larger output, stable performance.
---Pipe wall is average and smooth, to reduce waste of raw material, and pipe thickness is adjustable.
---No need trim edge, once forming.
---High degree of automation, can be operated by one person, saving labor costs.


1. High-effeciency single screw extruder
---Single screw is with barreir & mixing head; new model barrel with slotting (channel), Both make security of good jellification, large output and stable performance.



2. Die-Head
Die-head is mainly composed of mandril, neck mold, spiral body, cover, die-head body, bolts, and heating rings.
The inside surface touching with plastic materials is polished and chrome plated to ensure plastic materials flow smoothly and to ensure no rusting. The uniformity of pipe wall thickness can be adjusted by bolts. The copper calibrating sleeve fixed in die-head is mainly used to cool down the fresh pipe and to calibrate the pipe outer diameter.



3. Vacuum Calibration Tank
Vacuum calibration tank is mainly composed of frame, stainless steel tank, vacuum system, spray cooling system, position adjustment device. The vacuum pump exhausts the air from the sealed tank to pressurize the fresh pipe cling to calibrating copper sleeve and to calibrate the outer diameter. Spray nozzles spray cooling water from all directions on pipe surface to cool down the pipe promptly.




4. Haul-off Machine
Haul-off machine is mainly composed of driving device,track, clamping structure, adjusting system, side plate and foundation bed. Haul-off tracks are driven by AC motor with frequency conversion control to adapt to different extrusion speed.
Automatic length measuring device realizes cutting at a set length.


5. No-Dust Cutter
It adopts blade punching principle to realize no-dust cutting. It is mainly composed of cutting device, clamping device, structure synchronous movement device and frame.


6.Control system
The complete line could be controlled by PLC, with good human-machine interface, all technical parameters could be set and indicated by touching screen. Controlling system can be designed according to customers' requirements.


7.Discharging FrameThe table surface is made of stainless steel. It adopts pneumatic overturn and discharging automatically.
