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.
