ASTM A179 Carbon Steel Extruded Fin Tubes With Al1060 Fins For Air Cooled Condenser (ACC)
ASTM A179 This specification covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.ASTM A179 cold-drawn low-carbon seamless pipe is the most popular and cost-effective base pipe choice for extruded finned tubes (especially steel-aluminum extruded finned tubes). Its core advantages lie in four key aspects: processing adaptation, heat transfer, structure, and cost. It perfectly meets the process and working condition requirements of extruded fins.
Seamless structure: No weld seams, uniform wall thickness, avoiding cracking due to stress concentration at weld seams during compression and poor connection of fins.
The King of Cost Performance: Low-carbon steel combined with mature cold drawing technology. The price is only 1/3 to 1/5 of that of stainless steel / copper tubes. In non-severe corrosive conditions, the overall cost is the lowest.

Definition
Extruded finned tubes are bimetallic tubes whose outer aluminium surface is finned by cold plastic deformation.Extruded finned tubes have the following characteristics:1. High heat transfer performance, small contact thermal resistance;2. The contact area between the fin and the pipe is large, the fit is tight and reliable;3. Good corrosion resistance, stable long-term use performance;4. highly cost effective;5. The fin has good rigidity and is not easy to deform.
