ASME SA213 T9 Alloy Steel Studded Tubes for Heat Exchanger , Radiator
ASTM A213/ASME SA213 T9 Alloy Steel Studded Fin Tube refers to a type of Heat Exchanger Tube. The tube has studs attached to its outer surface, and these studs are typically made of a different material than the tube itself. Studded fin tubes are used to improve the efficiency of heat transfer in applications such as boilers, heat exchangers and air coolers. Studded fin tubes have studs welded on the base metal tube. The studs are arranged in a regular formation throughout the surface of the base tube. Studded fin tubes are usually applied in boilers and oil refineries because they increase the surface area for higher heat transfer. Studded Fin Tubes are mostly used in boilers and furnaces. Mostly in a corrosive environment. Studded fin tubes are widely used for heat transfer in the petrochemical industry for furnaces and boilers in which the surface is exposed to a high corrosive environment and in which dirty gas streams require frequent or aggressive cleaning.
ASTM A213/ASME SA213 T9. This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes. The studs on the base tubes increase the surface area, allowing for better heat exchange between the fluid inside the tube and the surrounding environment.
