ASTM A179 Carbon Steel Fin Tube Aluminiun G Fin Type For Dry Cooling Tower
Key Features of ASTM A179 Carbon Steel Fin Tube with Aluminum G-Fin:
Base Tube Material: ASME SA179 Carbon Steel
Seamless, cold-drawn low-carbon steel (C ≤ 0.06%).
High thermal conductivity and mechanical strength.
Compliant with ASME Boiler and Pressure Vessel Code (BPVC), ensuring suitability for pressurized systems.
Fin Material: Aluminum 1060
Pure aluminum alloy (99.6% Al) with excellent thermal conductivity (~230 W/m·K).
Lightweight, corrosion-resistant, and malleable.
Ideal for non-extreme environments due to its softness (lower mechanical strength compared to alloys like 3003 or 6061).
Embedded (G-Fin): Aluminum fins are mechanically bonded to the steel tube via a groove-and-collar process.
Extruded Fins: Fins are formed by extruding aluminum sleeves over the steel tube (common for softer alloys like 1060).
Ensures strong thermal contact while avoiding galvanic corrosion (with proper isolation).

Advantages of Using ASTM A179 Carbon Steel Fin Tube with Aluminum G-Fin:
High Heat Transfer Efficiency: Aluminum 1060’s superior thermal conductivity maximizes heat dissipation.
Cost-Effective: Aluminum 1060 is cheaper than higher-grade alloys, reducing overall costs.
Corrosion Resistance: Aluminum fins resist oxidation in dry or mildly corrosive environments.
Lightweight Design: Reduces structural load on air cooler systems.
ASME Compliance: SA179 tubes meet rigorous pressure and safety standards for industrial applications.
Typical Applications
Air Coolers in Refineries/Petrochemical Plants: Cooling process fluids (e.g., hydrocarbons, water).
Power Plant Air-Cooled Condensers: Dry cooling for steam turbines.
HVAC Systems: Heat rejection in chillers or refrigeration units.
Compressed Air Aftercoolers: Reducing compressed air temperature.
Why Choose This Combination?
SA179 Tubes: Reliable, code-compliant, and durable for pressurized systems.
Aluminum 1060 Fins: Optimizes heat transfer at lower cost in mild environments.
This setup is ideal for air coolers requiring high thermal performance without the need for extreme corrosion resistance or mechanical strength. For harsher environments, consider upgrading to aluminum alloys like 3003 or using protective coatings.
