ASTM A179 Carbon Steel Seamless Tube, Embedded Fin Tube with Aluminium Strip

Overview

This product combines ASTM A179 carbon steel seamless tube as the base tube and high-conductivity aluminium strip (usually Al1060) as the fin material. The aluminium fin is mechanically embedded into a helical groove on the outer surface of the tube, ensuring strong bonding and excellent thermal performance.

Chemical Composition & Mechanical Properties

Advantages

• Excellent Heat Transfer: Aluminium fins increase external surface area, improving thermal exchange rate.

• Anti-Corrosion: Embedded fin design avoids galvanic corrosion between dissimilar metals.

• Strong Bonding: Fins are tightly locked into grooves, offering durability in high-vibration environments.

• Lightweight: Combination of lightweight aluminium and carbon steel saves overall structure weight.

• Cost-effective: Ideal balance between performance and cost for mid-temperature operations.

Application of A179 Fin Tube

1. Air-Cooled Heat Exchangers

• Used in refineries, petrochemical plants, power stations, and chemical facilities.

• Ideal for dry-type air coolers, where water cooling is not practical or cost-effective.

2. Gas and Oil Furnaces

• Installed in convection sections of furnaces or heaters to enhance heat transfer between flue gas and process fluid.

3. HVAC Systems

• Applied in cooling coils and heating coils for commercial and industrial air conditioning or ventilation systems.

• Common in chillers, condensers, and evaporators.

4. Power Generation

• Used in steam condensers, air preheaters, and waste heat recovery units to improve energy efficiency and reduce fuel consumption.

5. Chemical and Petrochemical Plants

• Applied in process heat recovery, cooling towers, and condensation units.

• Ideal for operations where high-efficiency heat transfer and compact design are required.
