Embedded G Fin Tube Carbon Steel Seamless Tube ASTM A179 For Air Cooler, Cooling Tower
Description:
Embedded G fin tubes are manufactured by machining a helical groove onto the outer surface of the base tube. A pre-formed G-type aluminum fin strip is then wound into the groove and securely embedded, providing excellent mechanical bonding and stable heat transfer performance. This type of fin tube offers good resistance to fin loosening during thermal cycling and is widely used in air coolers, condensers, and cooling towers.
Materials:
Base Tube: Carbon Steel Seamless Tube ASTM A179
Fin Material: Aluminum Alloy (e.g., AL1060)
