PO pipe production with efficient IPC system

  • Significant reduction in cooling length due to IPC (Internal Pipe Cooling)
  • IPC system locally produced in China

As part of the recent Chinaplas 2014, the KraussMaffei Group held an open house and demonstrated the cost efficient production of HDPE pipes with a diameter of 630mm. The extrusion line featured a KME 90-36 B/R extruder and a KM-RKW 36-630 IPC pipehead as its core components, along with an internal pipe cooling system (IPC = Internal Pipe Cooling) which is produced locally.

This internal pipe cooling system is a first for the Chinese market, according to the company. By means of a side channel compressor, the IPC system sucks ambient air at high speed against the haul-off direction through the center of the pipe. As well as being cooled from the outside (using conventional processes with vacuum tanks and spray baths), the pipe is also cooled from the inside. This technology cuts the cooling zone by up to 40%. The advantages for processors: it reduces investment costs and saves space without any detrimental effects on output or production speed. In addition, the system contributes to resource savings during production, as it operates without the need for additional coolant and simply uses ambient air.
