Embedded G Finned Tubes
Embedded G fin tubes, also known as G-type finned tubes, are a type of extended surface fin tube used in various heat transfer applications.The fins are mechanically embedded into a groove that is plowed into the outer diameter (O.D.) of the base tube. This groove is typically about 0.4 mm deep.The fin strip, usually made of aluminum or copper, is tension-wound and placed into the groove. The bottom of the fin is then guided into the groove and backfilled with the base tube material to ensure a firm lock.
Processing technology: the fins are tightly embedded in the outer surface of the mechanically slotted base tube;
Base pipe material: carbon steel, alloy steel, stainless steel, duplex steel, copper pipe;
Fin: Aluminum 1060, aluminum 1100, T2 copper;
Application: air cooler, heat exchanger, heater, radiator economizer (Suitable for high temperature environment, limit temperature 350℃).
