Vacuum Calibration PU Pre-Insulated HDPE Casing Shell Jacket Pipe Extrusion Production Line
Product Description
The vacuum calibrationpolyurethaneinsulation pipe is a kind of high efficiencypre insulated pipe. It is mainly composed of working steel pipe, PUinsulation layer, plastic outer protective pipe and other parts.It is small in size, easy to operate with an automatic control system and has a long service life.The insulation material is rigid polyurethane foam, which fully fills the gap between the steel pipe and the casing and has a certain bonding strength. The steel pipe, outer pipe and insulation layer form a solid whole. It is applicable to insulation projects of various cold and hot water, petroleum, high and low temperature pipelines.
Product Parameters
Technological processes
---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
Performance and advantages
HUASHIDA insulation pipe production line performance
High-efficiency single screw extruder ---Single screw is with barrier & mixing head; new model barrel with slotting (channel), Both make the security of good jellification, large output and stable performance.
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 the die-head is mainly used to cool down the fresh pipe and to calibrate the pipe outer diame
Vacuum Calibration Tank The vacuum calibration tank is mainly composed of a 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 pipe surface to cool down the pipe promptly.
Haul-off Machine The haul-off machine is mainly composed of a driving device, track, 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.
Chipless cutting It adopts the 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 system The 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. ABB frequency converter or EUROTHERM speed controller Japan RKC temperature controller SIEMENS AC contactors A controlling system can be designed according to customers' requirements.
A 220ºC high-pressure foaming machine is used to inject polyurethane for foaming
