KraussMaffei Berstorff's new technology for internal pipe cooling reduces the initial cost and space requirements for a new pipe extrusion line, and boosts the productivity of existing pipe lines.
The system uses ambient air, sucked through the center of the pipe at high speed against the haul-off direction using a side channel compressor. IPC — used together with conventional external water cooling in vacuum tanks and cooling baths — cools the moving pipe gently from the inside.
The company said the technology can cut the required length of the cooling zone by as much as 40 percent. Or, keeping the cooling the same length as a traditional line, an IPC system can increase productivity by up to 60 percent over a conventional production line.
