The G fin tube consists of an aluminum fin strip that is mechanically embedded in the tube wall. The embedding process is controlled by tools that first plow a groove in the outer diameter of the tubes, then guide the base of the fin into the groove, and finally lock the fin in place by rolling the groove closed in the base of the fin. This ensures that maximum heat transfer is maintained at a high metal tube temperature of 400 degree C.
