ASTM A179 Embedded G-Type AL Carbon Steel Heat Exchanger Fin Tube
概述
ASTM A179 fin tubes are a type of heat exchanger tubes that are widely used in various applications.ASTM A179: ASTM A179 is a specification that covers minimum-wall thickness， seamless cold-drawn low-carbon steel tubes for heat exchangers， condensers， and similar heat transfer apparatus. These tubes are made from carbon steel and are designed to have excellent thermal conductivity.Fin Tubes: Fin tubes are created by attaching fins to the outer surface of the base tubes. The fins can be in the form of extruded， low-fin， or solid fins. Fin tubes increase the surface area of the tubes， enhancing heat transfer efficiency.
