G-Type Finned Tube Features:
In G-type finned tubes, the fins are prepared by embedding the metal strip into a groove. The latter is formed on a base tube. Placing the fin on it, back-filling is done – resulting in strong attachment of the fins to the base tubes. Hence, the name G-Fin Tubes has come up. The three processes mentioned above are carried out simultaneously. Maximum heat transfer is expected out of the g-fin tubes as the fins are strongly attached to the base tube.
The G-type finned tubes usually work at high temperature (with around 400 degree Celsius) applications. Made of copper, carbon, or aluminium, these fins have comparatively less resistance towards atmospheric corrosion. On the other hand, mechanical resistance is acceptable. Stainless steel and carbon steel fin materials are also used, but particular processing and tooling of the steel fin strips are necessary. Air coolers, radiators, etc use the g-fin tubes.

By not using a finned tube the outside surface area is not significantly greater than the inside surface area. Because of that, the fluid with the lowest heat transfer coefficient will dictate the overall heat transfer rate. When the heat transfer coefficient of the fluid inside the tube is several times larger than that of the fluid outside the tube the overall heat transfer rate can be greatly improved by increasing the outside surface area of the tube.
For applications that involve the transfer of heat from a hot fluid to a colder fluid through a tube wall, fin tubes are used. Usually, for an air heat exchanger, where one of the fluids is air or some other gas, the air side heat transfer coefficient will be much lower, so additional heat transfer surface area or a fin tube exchanger is very useful. The overall pattern flow of a finned tube exchanger is often crossflow, however, it can also be parallel flow or counterflow.
Fins are used to increase the effective surface area of heat exchanger tubing. Furthermore, finned tubes are used when the heat transfer coefficient on the outside of the tubes is appreciably lower than that on the inside. In other words, heat transferred from liquid to gas, vapor to gas, such as steam to air heat exchanger, and thermic fluid to air heat exchanger.
