This line is mainly used for producing PVC pipes with diameter 50,
75mm, 90mm, 110mm, 125mm, 160mm. By changing the mandril, it can
produce pipes with different pipe wall thickness. With different
mold, it can also produce PVC silent pipes. 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 adopt two chamber structure: the vacuum calibration
and cooling parts. Both of them 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 two or 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.
