A finned pipe is a tube that transfers heat from hot fluid to cooler fluid through the tube wall. By increasing the outer surface area of the tubes, the overall heat transfer rate increases, thereby reducing the total number of tubes required. In many cases finned tubes replace six or more bare tubes at 1/3 the cost and 1/4 the cost.

What is a steel fin tube?
Fin tubes are mainly used in high temperature conditions and corrosive atmospheric conditions, such as boiler economical parts, heat exchangers and convection sections of process heaters and oil coolers. Common application areas are: Energy Industry Chemical and Petrochemical Industry Food Processing and Refrigeration Industry Oil and Gas Industry
