Impact of sulfate reducing bacteria on biocorrosion of pipeline steels

Abstract

Samples obtained from natural gas pipelines were used directly for determine the regularities in corrosion steels 17G1S-U and 20 under the influence of sulfate-reducing bacteria (SRB) of type Desulfovibrio sp. strain Kyiv-10 and their relation to the microstructure of steel in condition that simulated a natural gas pipeline environment. Microbiological corrosion induced by SRB of pipeline steel 17G1S-U and steel 20 were studied. The impact of the inhibitors nature on the specimen protection degree under the development of anaerobic corrosion under the influence of SRB is investigated.
