Product Description

Vacuum Calibration HDPE Plastic Pipe Polyurethane Pre-Insulated Pipe Production Line 

HDPE Plastic Pipe Polyurethane Pre-Insulated Pipe Production 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.


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







 ---Pipe Usage: the outer casing of thermal insulating pipe, which is widely used in central heating, oil, natural gas and other industrial areas.
---Pipe/jacket diameter range: 110-1200mm




Die-head
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.



Vacuum Calibration Tank
The 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 calibrate the copper sleeve and to calibrate the outer diameter.  Spray nozzles spray cooling water from all directions on the pipe surface to cool down the pipe promptly.



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



 No-Dust Cutter
It adopts blade punching principle to realize no-dust cutting. It is mainly composed of a cutting device, clamping device, structure synchronous movement device and frame.
Control systemThe complete line could be controlled by PLC, with the good human-machine interface, all technical parameters could be set and indicated by touching the screen. A controlling system can be designed according to customers' requirements.
