Low fin tubes are generally machined to form fins of a certain height, a certain fin pitch, and a certain thickness on the outer surface of the light tube.

Mainly used in air-conditioning and refrigeration equipment (condensers, evaporators), the heat exchange efficiency is improved by increasing the surface area. It is also used in high-temperature and high-pressure scenarios such as boilers and electricity in the industrial field, but the search results do not clearly mention specific application cases. ‌

Common materials include carbon steel, em aço inoxidável, copper, aluminum alloy, etc., among which stainless steel 304/316, duplex steel 2205 and other materials can adapt to more complex working conditions. Parameters such as fin height and fin pitch are controlled through process to optimize heat exchange performance and anti-deformation ability.
