ASTM A179 / ASME SA179 Seamless Carbon Steel Tube Low Fin Tube for Heat Exchanger
Low finned tubes have finning that runs the length of the tube with low height fins, which significantly increases the surface area available for heat exchange without greatly increasing pressure drop. The increased surface area provided by the fins on low finned tubes enhances heat transfer efficiency, making them particularly effective in applications where compact heat exchangers are required. They are commonly used in air conditioning, refrigeration, heating, and process industries where efficiency and space constraints are crucial.
