Concept Of Finned Tubes

  Finned tube, in order to improve efficiency, usually in a heat exchanger surface through the fin, increased heat exterior surface area (or internal surface area), so as to achieve the objective of improved efficiency, such a tube.

  Fin-and-tube heat transfer components, work under the condition of high temperature flue gas for a long time, such as boiler heat exchanger with finned tubes for use of environment, high pressure and high temperature and corrosive atmosphere, this calls for fin-and-tube should have a high level of performance. First, strip the plane perpendicular to the axis of the tube in a spiral way around on the outer surface of the pipe and strip both ends fixed on the welded steel pipe, and steel and steel pipe contact point for clearance, using brazing method to steel and steel tubes welded together.
