^{Product Description}

^{The Imbedded Fin, also known as a G-fin (grooved fin), is widely used throughout the world. This fin is considered to have a mechanical bond to the tube and has negligible deterioration of the fin bond with heat cycling. The fin is usually specified for high temperature applications with the fin material being the limiting factor. Typically, this fin is produced out of aluminum or copper fin strip. This fin type is also suitable for carbon steel or stainless steel fin materials, but requires special tooling and processing of these steel fin strips.}

^{Preforming is not required for aluminum fin on carbon steel tubes, but is required for copper or steel fin and in the case of aluminum fin on aluminum tubes. Dovetail rollers are used to preform the fin and facilitates insertion into the groove. When standard groove depth is used for aluminum or copper fin strip, the fin strip width is always .012” larger than the fin height, i.e. .625” plus .012” = .637”.}

^{G Finned Tube Manufacturing Process:}

^{The manufacturing tool is made up of 2 non-cutting plates set at 90° to the axis of the base tubes (pipes) (core tube).The first plate effects a groove for metal spinning. The second directs the ribbon in the groove and sets the fin foot in the groove through pressure on the metal displaced for the groove. A similar plate made of tungsten carburate allows us to manufacture. G embedded fin tubes ( fin tubes )with base tubes (pipes) (core tube) made of austenitic steel or exotic alloys.}

^{G Finned Tube Advantages:}

^{High fin stability, excellent heat transfer, high operating temperature.}

^{The fin/tube wall contact is constant because of the setting and makes it possible to use a wall temperature of up to 450°C.}

^{The fin is set throughout its length and consequently does not unwind even when partially uprooted.}

^{This kind of finned tube is one of optimum choices for having good effectiveness/cost ratio.}
