Controlling Microbiologically Influenced Corrosion in Pipelines
By Gretchen Jacobson, Materials Performance Managing Editor, NACE International Microbiologically influenced corrosion (MIC) refers to corrosion caused by the presence and activities of microorganisms – microalgae, bacteria, archaea, and fungi. While microorganisms do not produce unique types of corrosion, they can accelerate corrosion reactions or shift corrosion mechanisms. Microbial action has been identified as a contributor to rapid corrosion of metals and alloys exposed to soils; seawater, distilled water, and freshwater; crude oil, hydrocarbon fuels, and process chemicals; and sewage. Many industries and infrastructure are affected by MI
