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.
