Guidelines to control MIC in new buried steel pipeline construction. L. Manion. Pipeline Gas J., October 1998, 225(10), 30--32.
Various types of microbiologically influenced corrosion (MIC) of steel pipelines are discussed. The micro-organisms are single cell plants that survive under adverse conditions and when active they multiply with incredible speed. Some types of sulphate reducing bacteria remove steel at a penetration rate of 0.5 in. per year. Effects of aerobic, anaerobic, and facultative bacteria are discussed. Mechanisms of MIC attack are discussed and methods of prevention are reviewed. A combination of cathodic protection and protective coatings is recommended as a cost-saving technique to combat MIC in most new construction projects.
