Finned pipes is a pipe that transfer heat from a hot fluid to a colder fluid through a tube wall.By increasing the outside surface area of the tube,the overall heat transfer rate increased,thereby reducing the total number of tubes required.In many cases, one finned tube replaces six or more bare tubes at less than 1/3 the cost and 1/4 the volume.
