ASME SA179 Aluminum Extruded Finned Tubes are designed for industrial air-cooled heat exchangers requiring efficient heat transfer and reliable fin-to-tube bonding. Manufactured with seamless cold-drawn SA179 low-carbon steel base tubes and mechanically extruded aluminum fins, these bimetallic tubes provide an enlarged external heat transfer surface while maintaining good thermal contact between the fins and base tube. They are suitable for cooling process fluids, lubricating oil, compressed air, and industrial gases in applications where air-side heat transfer is a major design consideration. The aluminum outer layer also provides additional protection to the steel base tube against atmospheric exposure. Custom dimensions, fin configurations, and tube lengths are available according to project specifications.

Application & Compliance

Air-Cooled Heat Exchangers

Used in refinery and petrochemical cooling systems to reduce process fluid temperatures without relying on cooling water.

Compressor Intercoolers & Aftercoolers

Applied in compressed-air and industrial gas cooling systems to improve heat dissipation and cooling efficiency.

Oil Coolers

Suitable for lubricating oil and hydraulic oil cooling systems where increased air-side heat transfer area is required.

Industrial Gas Coolers

Used for cooling non-corrosive process gases in industrial heat exchange equipment.

Application Benefits

Enhanced Heat Transfer: Enlarged aluminum fin surfaces improve air-side heat transfer performance.
Reliable Fin Bonding: Mechanical extrusion provides close contact between the aluminum fins and steel base tube.
Corrosion Protection: The aluminum outer layer offers additional atmospheric protection to the carbon steel base tube.
Water Conservation: Suitable for air-cooled systems that reduce dependence on cooling water.
Custom Manufacturing: Tube dimensions, fin geometry, and overall lengths can be customized to meet project requirements.

As an engineer in Siberia, I tested these fin tubes in extreme cold (-30°C). The ASTM A213 T11 steel performed well with no thermal cracks, and cooling efficiency met expectations (88%). That said, the Russian-language documentation had translation errors in technical terms, causing minor confusion during installation.

Quality is top-tier, and the price is very competitive compared to others. Most importantly, the SA249 TP304 wall thickness is uniform and the welding looks beautiful.
