Product Description

G Type Embedded Finned Tubes ASTM A179 Carbon Steel For Boiler Economizers

ASTM A179 specifies the requirements for seamless cold drawn, low carbon steel tube intended for high-temperature service, like heat exchangers, condensers and heat transfer equipment.

A179 exhibits good weldability, ductility, and resistance to steam and corrosion.

Outer diameter range: Ideal for air coolers and shell-and-tube heat exchangers ≤76.2 mm / 3".

The Al1060/1100 fins are mechanically interlocked and fixed within pre-machined spiral grooves on the outer wall of the A179 tube.

The thermal resistance between the fins and the base tube is extremely low. The maximum operating temperature can reach 350℃ (significantly higher than L/KL wound finned tubes). The fin structure is stable, exhibiting excellent resistance to vibration, thermal cycling, and thermal expansion. The fin surface is smooth, making it easy to clean and remove accumulated dust. It offers a large heat exchange area while maintaining a small footprint.

Low-carbon steel base tubes with aluminum fins are used for gas-side heat exchange; perfectly matched for flue gas, hot air, and steam cooling/heating, offering high cost-effectiveness.

Key Application

1.Power Generation Industry (Largest Application Scenario)

Air-Cooled Condenser (ACC)

Boiler Economizers & HRSG (Heat Recovery Steam Generator)

2.Petrochemical & Refinery Industry (API 661 Standard Air Coolers)

Crude oil refining: process air coolers, reactor feed coolers, distillation column condensers

Natural gas dehydration, amine desulfurization & acid gas treatment units

3.Metallurgy & Heavy Industry

Air Cooled Heat Exchangers (ACHE / ACC)

Shell & tube waste heat recovery exchangers

Waste heat boiler evaporation & cooling sections

Industrial drying radiators

Compressor cooling units

ASTM A179 low-carbon steel base tubes are not suitable for strong acids, strong chloride brine, or highly corrosive media. For severely corrosive conditions, the base tube should be replaced with stainless steel (TP304/316L) or alloy steel (A213 T11/T22) G-type finned tubes.We also can offer finned tubes of these materiales.

The finning is tight — you can tell they used a proper cold-forming process because the fins don't move at all when you try to wiggle them. We've had issues before with other suppliers where the fins would come loose after a few thermal cycles, but these ones feel solid.
