A test methodology was developed by means of which flow induced localized corrosion (FILC) could be generated in the laboratory in 100 hour tests. In order to develop inhibitors which are effective under high fluid flow rates, it was necessary to simulate in the laboratory not only the field parameters, but also the corrosion morphology observed in the field. It was found that this is possible with the rotating cage method. The effects of temperature, chloride concentration, and metallurgy will be discussed. The rate of attack in all cases shows a steep maximum at about 200 to 250°F, however, the severity of localized corrosion depends in large measure on minor alloying elements in the carbon steel. A mechanism for FILC is proposed.
