Stainless steel heat exchanger tube is generally used for boiler, heat exchanger, and condenser, standards are A249 welded tube and A213 seamless tube, 304 / 304L, 316 / 316L, 310S, 2205, S31803 stainless steel grades, annealing pickling or bright annealing condition.
Stainless steel tube has high temperate resistance and corrosion resistance, are used for heat transfer processes and are mostly applied in heating, cooling, condensation and evaporation of liquids, gases and steam.
We offer a range of alloys that deliver high strength, thermal conductivity, and corrosion-resistant properties to ensure optimum performance in extreme conditions.
Heat exchanger is a device used to transfer heat between a solid object and a fluid, or between two or more fluids at different temperatures, transfer heating from higher temperature fluid to lower temperature object to make fluid temperature to specified requirement, for stainless steel grades, there are shell and tube heat exchanger, plate heat exchangers, plate and shell heat exchanger and other heat exchanger, tube heat exchanger consists of a number of tubes inside bundle and sheet, widely used in many industries.
