Product Description

ASTM A249 covers nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from austenitic steels with various grades intended for 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.

Available Materials

Base tubes: carbon steel, copper, alloy, stainless steel
Fins: copper, aluminum 1060/1070, aluminum alloy 6063/6061

Categories of Wound Finned Tubes

L-fin tubes
LL-fin tubes
KL-fin tubes

Key Advantages

Trapezoidal section formed by rolling of L-shaped finned tube matches heat flow density distribution
Eliminates contact thermal resistance caused by gaps between fins
Compact design allows for more efficient heat exchanger configurations
Welded stainless steel base tubes provide robust construction resistant to mechanical damage

Applications

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.
