large diameter PVC pipe extrusion line
This line is mainly used for producing UPVC pipes with large
diameters and different pipe wall thickness in the aspects such as
the agricultural and constructional plumbing, cable layietc. The
max diameter of pipe could be 1200mm.
The process flow of this line as blow:
PVC powder + additive --- mixing---material feeder---twin screw
extruder---mould and calibrator---vacuum forming machine---spraying
cooling machine---haul-off machine---cutting machine---discharge
rack or pipe belling machine.
The screw of extruder has advanced design, which provide powerful
safeguard for the PVC plasticization, and the Siemens PLC control
system make more convinient operation. The degassing system will
ensure the quality of final PVC pipes.
The tank body of vacuum calibration and cooling units adopt
stainless 304# steel, multi-sections vacuum system ensures the
stable sizing and cooling for pipes; Special cooling system
improves the cooling efficiency; Auto water temperature control
system make the machine more intelligent.
For different pipe size, the haul-off machine will adopt two
caterpillars, three caterpillars, four caterpillars, six
caterpillars are designed for different requirements. Pedrail
clamping uses mechanical and pneumatic combining system, which is
more reliable in performance
Cutting system adopts no-dust cutter or planetary cutting means;
There is dust-collecting system ensures clean working environment.
