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.

Welded stainless steel tube for heat exchanger

ASTM A249/SA249 is a specification for welded stainless steel heat exchanger tube in heating system, annealing pickling or bright annealing finishing, tube welding bead should removed and grinding inside and outside to ensure smooth surface, it is easy to clean inside heat exchanger, DONGSHANG Stainless is a welded stainless steel tube suppliers which can offer U bend tube and coiling tube for various type heat exchangers.

Seamless stainless steel tube for heat exchanger

ASTM A213 is a specification for seamless stainless steel heat exchanger tube, covering kinds of stainless steel grades to meet various requirement, minimum wall thickness or average wall thickness as agreement, cold drawn and cold rolled finishing, control tolerance of outside diameter, wall thickness and length, testing and inspection as standard should be carried out to make high quality heat exchanger tubes.

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.
