Embedded G Finned Tubes
Embedded G fin tubes, are mechanically embedded into a groove that is plowed into the outer diameter of the base tube. This groove is typically about 0.4 mm deep.The fin strip is tension-wound and placed into the groove.
Base tube material: carbon steel, alloy steel, stainless steel, duplex steel, copper tube;
Fin: Aluminum 1060, aluminum 1100, T2 copper;
Application: air cooler, heat exchanger, heater, radiator economizer (Suitable for high temperature environment, limit temperature 350℃).
