Influence of soil microorganisms on metal corrosion of underground pipelines

Résumé : There have been revealed and summarized the regulari- ties in biocorrosion of steel 17G1S-U, which is traditionally used for manufacturing oil and gas mains. The basic regulari- ties of biocorrosion processes in the 17G1S-U pipe steel under the influence of SRB Desulfovibrio Sp. strains Kyiv-10 was ob - tained by weight-loss testing and surface analysis techniques. Effective inhibitors are proposed, which allow protecting ste- el 17G1S-U against the development of anaerobic corrosion under the influence of sulfate-reducing bacteria (SRB). The effectiveness of inhibitors is estimated by the degree of their protective effect. The porous structure of the surface film con - tributes to the initiation of localized corrosion. Damage analy- sis of the specimen surface corroded under different test condi- tions was performed.
