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