Carbon Steel ASTM A179 G Type Embedded Fin Tube For Air Cooler
Carbon Steel Fin Tube ASTM A179 G Type, Embedded Fin Tube, For Air Cooler
Introduction
This G-Type Embedded Fin Tube is manufactured with a carbon steel seamless tube (ASTM A179) as the base and high-purity aluminum strip (Al1060) as the fin material. The G-type design features fins mechanically embedded into a groove cut in the base tube, offering superior mechanical bonding and enhanced heat transfer efficiency. It is ideal for air-cooled heat exchangers used in demanding industrial applications.
