Embedded G fin tubes The fin strip is wound into a machined groove and securely locked into place by back filling with base tube material. This ensures that maximum heat transfer is maintained at high tube metal temperatures.
Embedded fins (G Fins) are made by winding aluminium or copper strip into a helical groove machined on the outer surface of the tube.
