A finned tube is a kind of heat exchange element. It is a kind of heat exchanger tube to improve the heat transfer efficiency, usually by adding fins on the surface of the heat exchanger tube to increase the external surface area (or internal surface area) of the heat exchanger tube, so as to achieve the purpose of improving the heat transfer efficiency.

ASTM A588 steel pipe is a commonly used high-strength low-alloy structural steel that is widely used in construction, bridges, vehicles and other fields.

ASTM A213 T92, T22, and T5 heat exchanger tubes are seamless alloy steel tubes used for heat exchangers in high temperature and high pressure environments.
