The Involvement of Bacteria in the Failure of a Carbon Steel Pipe

Abstract:

In the raw water a lot of bacteria who play an important role in the corrosion of steels are present. These bacteria may initiate or accelerate corrosion processes because they are able of inducing localized changes in the aqueous environment, in terms of pH and oxygen concentration, destroying protective layers or creating corrosive deposits. This paper presents a study on the involvement of bacteria in the degradation of a pipe from raw water cooling system. Microbiological analysis of sampled sludge from internal surface of pipe emphasized the existence of some microorganisms: heterotrophic aerobe bacteria, iron oxidizing bacteria and sulphate-reducing bacteria. Investigation techniques of microbiologically influenced corrosion included metallographic analysis of the surface and X-ray diffraction analysis of samples taken from existing deposits. The results emphasized that the change of environmental chemistry under the developed biofilm by the bacteria, together with the corrosive products as a result of the metabolic activity of the bacteria, influenced the perforation of the pipeline.
