L-Type Wound Fin Tubes Carbon Steel ASTM A179 Base Tube With Aluminum Fins
L-Type wound fin tubes are a type of heat exchanger tube used in various industrial applications to enhance heat transfer efficiency. They are characterized by fins that are wound around the base tube in an "L" shape, which increases the surface area for heat exchange.General materials of base tubes of wound finned tube are carbon steel, copper, alloy, stainless steel ; general materials of fins of wound finned tube are copper, aluminum 1060/1070, aluminum alloy 6063/6061.
ASTM A179 covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.

| A179 | 47ksi (325 MPa) | 26ksi (180 MPa) | 35% |
Advantages
Allows for more efficient use of space in heat exchanger designs.
The fins increase the surface area, improving the heat transfer rate between the tube and the surrounding medium.
Enhances the efficiency of heat exchange processes, potentially reducing operational costs.The fins are typically made from materials that resist corrosion and wear, ensuring a long service life.
