Extruded fin tubes can be manufactured using various materials, depending on the application:Base Tube Materials---Carbon steel, stainless steel, copper, titanium, and alloys;Fin Materials--- Aluminum (common for corrosion resistance and lightweight properties) or the same material as the base tube.
Extruded fin tube is crucial for enhancing heat transfer efficiency in various industrial and HVAC applications.Not only enhance heat transfer efficiency but also improve air-side heat transfer.Below are applications in air cooling systems:
*HVAC Systems: Used in air handlers, condensers, and evaporators.
*Industrial Air Coolers (Fin-Fan Coolers): For process cooling in refineries, power plants, and chemical industries.
*Refrigeration & Heat Pumps: Enhances condenser and evaporator performance.
*Automotive & Aerospace: Charge air coolers, oil coolers, and radiator systems.
Conclusion
ASTM A179 is a standard specification for seamless cold-drawn low-carbon steel tubes used in heat exchangers and condensers, air coolers. Extruded fin tubes are a high-performance solution for air-cooled heat exchangers, offering durability, efficiency, and compact design, typically tubes with aluminum extruded fins,these tubes become highly efficient for air-cooling applications.A179 material has high thermal conductivity and good resistant to stress corrosion cracking.
