ASTM A179 carbon steel wound L fin tubes with Al1060 aluminum fins are high-efficiency heat transfer components specially designed for air cooled heat exchangers. The base tube is manufactured in accordance with ASTM A179/A179M, which specifies cold-drawn low-carbon seamless steel tubes with good thermal conductivity and mechanical strength suitable for heat exchange service.

The fins are made of 1060 pure aluminum (Al ≥99.6%), featuring ultra-high thermal conductivity, excellent formability, and corrosion resistance in low-temperature environments.

L-shaped fin strip is tightly wound onto the outer surface of the base tube under controlled tension, forming a stable and low thermal resistance bonding structure. This type of finned tube significantly increases the external heat transfer area, strengthens flue gas turbulence, and effectively recovers waste heat from low-temperature boiler flue gas to heat feedwater. It helps reduce exhaust gas temperature, improve overall boiler efficiency, and save fuel consumption.

Advantages

High Heat Transfer Efficiency:

L-shaped fins maximize external surface area, significantly improving air-side heat transfer.

Cost-Effective Performance

Good Mechanical Bond:

Tension-wound design provides strong fin-tube contact, resisting vibration and thermal cycling in air-cooler service.

Compact & Lightweight Design:

Under the same heat transfer requirement, the L-type wound fin tube has a smaller volume and lighter weight than traditional bare tubes or other types of finned tubes.

Corrosion Protection:

Fins shield the carbon steel base tube from direct atmospheric exposure in air-cooled environments.

Good strength, handles the pressure, no corrosion issues so far. We're running treated water, so no complaints.

Good oxidation resistance, matches well with the T9. No scaling or thinning noticed.

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.
