First in the world for the quick and efficient spot reduction of heavy wall carbon and alloy tubing in refinery heat exchangers, FinFan coolers and other tubular vessels. This unique system safely reduces the tube wall in the form of a slot so that a One Revolution Tube Cutter can then pierce and cut a ventilation slot at the appropriate 90 or 180 degrees, prior to plugging the leaking tube. Mini Wall reducer uses one cutting bit and can be used for any material tubes.

MWR on regular tube sheet

On standard heat exchangers machine locks onto two shafts on the adjacent holes. The locking plate is manufactured according to the tube hole pitch to ensure precise tool alignment.
