ASTM A179 Carbon Steel Extruded Fin Tubes With Al1060 Fins For Air Cooled Condenser (ACC)
ASTM A179 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 tube is the most popular and cost-effective base tube choice for extruded finned tubes, particularly steel-aluminum extruded finned tubes. Its core advantages include processing adaptation, heat transfer efficiency, structural integrity, and cost-effectiveness, perfectly meeting the process and working condition requirements of extruded fins.
Key Advantages
Seamless Structure: No weld seams, uniform wall thickness, avoiding cracking due to stress concentration at weld seams during compression and ensuring reliable fin connection
Superior Cost Performance: Low-carbon steel combined with mature cold drawing technology provides pricing at only 1/3 to 1/5 of stainless steel or copper tubes, delivering the lowest overall cost in non-severe corrosive conditions

Extruded Fin Tube Definition
Extruded finned tubes are bimetallic tubes whose outer aluminium surface is finned by cold plastic deformation. These tubes feature:
High heat transfer performance with minimal contact thermal resistance
Large contact area between fin and tube with tight, reliable fit
Excellent corrosion resistance and stable long-term performance
Superior cost effectiveness
High fin rigidity with minimal deformation risk
Extruded Fin Tubes Applications
Air-cooled heat exchangers & air coolers
Air cooled condensers (ACC) in power plants
Oil coolers & hydraulic system coolers
Gas coolers & compressor intercoolers
Furnace waste heat recovery equipment
Petrochemical & refinery heat exchange units
HVAC & refrigeration heat exchangers
Heat pumps & energy-saving heat transfer equipment
Marine heat exchangers & shipboard cooling systems
