Corrosionpedia - What is Flash Steam? - Definition

Flash steam is the steam that is generated from a hot condensate when the pressure within a pipe decreases. Flash steam is the same as normal steam, except that flash steam is produced when the stream is exiting a boiler or steam generator and there is a pressure drop at the boiler's outlet (i.e., the exit of the steam trap).
