Wound L Fin Tubes ASTM A249 TP304 Welded Base Tube With AL1060 Fins
ASTM A249 cover nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels with various grades intended for such use as boiler, superheater, heat exchanger, or condenser tubes.
ASTM A249 TP304 tubes are essential for applications requiring excellent corrosion resistance and high-temperature strength. Their composition and mechanical properties make them suitable for critical components in boilers, superheaters, heat exchangers, and condensers. The material's hygienic properties also make it ideal for use in the food, beverage, and pharmaceutical industries.

Wound fin tubes are a type of heat exchanger tube that features fins wrapped around the outer surface of the tube. The fins are typically made from materials like aluminum or copper and are wound in a helical or spiral pattern. This design increases the surface area of the tube, enhancing its ability to transfer heat between the fluid inside the tube and the surrounding environment.
General materials of base tubes: carbon steel, copper, alloy, stainless steel
General materials of fins: copper, aluminum 1060/1070, aluminum alloy 6063/6061
Three categories of wound finned tubes: L-fin tubes, LL-fin tubes and KL-fin tubes.
Advantages
The trapezoidal section formed by rolling of L-shaped finned tube is consistent with the distribution of heat flow density, and the tubes are closely combined with high thermal efficiency, thus eliminating the contact thermal resistance caused by the gap between the fins.
The compact designs of fin tubes allows for more compact heat exchanger designs.
Welded stainless steel base tubes has robust construction, which resistant to mechanical damage.
Application
Wound L-type fin tubes are used in heat exchangers for air cooling or heating fluids such as air, water, oil, or gas. They are commonly found in industries such as oil & gas, power generation, marine, and HVAC&R.
Diesel Charge Air Coolers / Oil Coolers / Hydrogen Coolers
Waste Heat Recovery
Driers
Air Conditioning / Air Heaters
Generator Coolers
Steam Condensers
Conclusion
Wound L-fin tubes are crucial components in various heat exchange applications, offering enhanced thermal performance and durability.The L-shaped fin design provides a larger surface area, significantly improving heat transfer efficiency.Their design and material selection are tailored to meet specific operational requirements, making them indispensable in industries ranging from power generation to chemical processing.
