75~250mm PVC pipe extrusion production line
This line is mainly used for producing PVC pipes with diameter
75mm, 90mm, 110mm, 125mm, 160mm, 180mm, 200mm, 225mm, 250mm. By
changing the mandril, it can produce pipes with different pipe wall
thickness. PVC pipes can use for the aspects such as the
agricultural and constructional plumbing, cable laying etc. The
process flow of this line as blow:
PVC powder + additive --- mixing---material feeder---twin screw
extruder---mould and calibrator---vacuum forming machine---haul-off
machine---cutting machine---discharge rack or pipe belling machine.
The screw of the extruder could be designed as lower filler screw
and high filler screw. With advanced design, it provide powerful
safeguard for the PVC plasticization. There is degassing system for
the screw and barrle, which will ensure the quality of final PVC
pipes. The motor adopt Siemens standard motor, ABB inverter,
Siemens PLC control system.
The tank body of vacuum calibration and cooling units adopt
stainless steel 304# . The excellent vacuum system ensures the
precise sizing for pipes; spraying cooling will improves the
cooling efficiency; Auto water temperature control system make the
machine more intelligent.
The haul-off machine of this PVC pipe line will adopt three
caterpillars, and the compact mode of haul-off frame adopt
pneumatic and gear motor. With meter code, it can count the pipe
length during the production.
Cutting system adopt PLC control and it could be no-dust cutter and
planetary cutter. There is dust-collecting system ensures clean
The pipe belling machine can make pipe with different belling
shape, such as "U" type, "R" type etc. We can also design pipe
belling machine with auto rubber ring feeding system.
