[0002] Finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added to the surface of the heat exchange tube to increase the outer surface area (or inner surface area) of the heat exchange tube, thereby achieving the purpose of improving the heat exchange efficiency. As a heat exchange element, finned tubes work under high-temperature flue gas conditions for a long time. For example, the finned tubes used in boiler heat exchangers are used in harsh environments, high temperature and high pressure, and in a corrosive atmosphere, which requires the finned tubes to have very high performance indicators.
