Stainless Steel Heat Exchanger Tube
Stainless steel heat exchanger tube is generally used for boiler, heat exchanger, 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, used for heat transfer processes and mostly applied in heating, cooling, condensation and evaporation of liquids, gases and steam. Heat exchanger tubes are always cold finished condition and resistant to corrosion.Basic specification.

Heat Exchanger Applications
Heat exchanger is a device used to transfer heat between a solid object and a fluid, or between two or more fluids in different temperature, 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.- space heating
- refrigeration
- air conditioning
- power stations
- chemical plants
- petrochemical plants
- petroleum refineries
- natural-gas processing
- wine and beer making
