Tests were run to assess the feasibility of a MIC mitigation treatment for stainless steel piping that would not require access to the inside of the pipe. Laboratory test runs indicated that heating the unexposed surface to produce temperatures of 165°F (74° C) or higher on the exposed surface produced shifts in the open circuit potential to levels the same as those experienced upon initial exposure to the seawater test environment. External heat treatment may be feasible in the field to mitigate existing MIC.
