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.

Mechanical Properties

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.
