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 A252 pipe piles are typically used in construction projects involving deep foundations, such as bridge and building construction, marine structures, and retaining walls.
