Product Description

ASTM A179 Carbon Steel Wound L Fin Tube With Al1060 Fins for Boiler Systems Economizers

ASTM A179 carbon steel wound L fin tubes with Al1060 aluminum fins are high-efficiency heat transfer components specially designed for economizers in boiler systems. 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 flue gas 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.This L type of fin tubes is widely used in low-temperature economizers of industrial boilers and utility boilers, especially suitable for working conditions where the flue gas temperature is generally below 150℃, with low dust content and non-corrosive medium.

Advantages

High Heat Transfer Efficiency:

L-type wound fin design significantly expands the heat transfer area (8-12 times that of bare tubes) and disturbs the flue gas flow, breaking the laminar boundary layer and increasing the heat transfer coefficient by 40-60%, thus realizing efficient waste heat recovery in low-temperature economizers.

Cost-Effective Performance

Excellent Corrosion Resistance & Long Service Life:

In the low-temperature flue gas environment of boiler economizers (usually ≤ 150℃), the Al1060 fins can naturally form a dense oxide film on the surface, effectively resisting sulfur corrosion and condensation corrosion. The ASTM A179 carbon steel base tube has moderate strength (tensile strength ≥ 325 MPa, yield strength ≥ 180 MPa) and good pressure resistance, which can withstand the working pressure of boiler feedwater and ensure long-term stable operation.

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.

Strong Adaptability to Working Conditions:

This product is specially designed for boiler economizers, perfectly matching the working conditions of low-temperature flue gas (120-300℃) and boiler feedwater/condensate (20-150℃). It is widely applicable to low-temperature economizers and waste heat recovery systems of power station boilers and industrial boilers, and can replace traditional bare tube economizers and some G-type/LL-type finned tubes, with strong versatility and adaptability.

Very professional team, easy to talk to. We had some specific size requirements and they nailed it. The TP304 stainless tube with aluminum fins works like a charm for heat dissipation. Thumbs up!

Cost and reliability are key for Indian refineries. We installed these fin tubes in Mumbai’s cooling towers, achieving 16% energy savings versus local suppliers. ASTM A213 T11 compliance ensured no failures during monsoon humidity (90%+ RH), and the low price saved $8K upfront.
