The German company, Krauss Maffei Extrusion has introduced a new system for internal pipe cooling (IPC) that significantly reduces the initial cost and space requirements for new Polyolefin (PO) pipe extrusion lines.  

The IPC system increases productivity by up to 60% if the existing line length is maintained and can also be retrofitted to existing pipe extrusion lines. Significant energy savings are also achieved with the pipe cooling system.  

Krauss Maffei’s internal pipe cooling system uses ambient air, which is sucked through the centre of the pipe at high speed against the haul-off direction by means of a side channel compressor.  

Combined with conventional external water cooling in vacuum tanks and cooling baths, the IPC system cools the pipe gently from the inside.  

Ideal for space-constrained factories, the IPC can reduce the length of the cooling zone by as much as 40% resulting in floor space savings without compromising production speed.  

The internal pipe cooling system is suitable for the production of thick walled pipes where standard cooling methods are ineffective in removing heat from the extruded pipe.  

Similar to conventional pipe extrusion lines, the melt flows directly from the extruder into the pipe head, avoiding the problems of lateral melt feed.  

Continuous monitoring and active control of the air suction volume adjusts conditions to ensure uniform cooling performance, which guarantees consistency in product quality.  

A key benefit of the IPC system is the substantial energy saving as the system uses ambient air and does not require the use of other cooling media.  

The IPC system is suitable for all PO pipe extrusion lines from 110mm to 2,500mm in diameter.
