Suppressing sulfate-reducing bacteria, as well as hydrogen diffusion through steel, by inhibitors of AMDOR IC type

Assessment of inhibiting features of some commercial bactericides

“…Both underground and above-ground constructions, petroleum and gas industrial equipments, shore and harbour installations, pipelines in contact with ground and water environment, are subject to the corrosion. Such biodamages can reduce service life and safety of constructions and equipments, lead to their failures and unsafe operation, impose significant economical and ecological damage [2].…”

“…In this connection, studies on biocorrosion impacts on pipe steel under detached protective coating in underground lengths of long-time operated TGP are of particular interest. Theoretical conceptions of microbiological corrosion processes have been discussed more than once in engineering literature; this topic can be found both in domestic [2,4], and in world periodicals [5][6][7][8], and also it is routinely discussed at international scientific forums [9,10]. Authors of papers involved, would specifically mention evident corrosion activity by sulphate-reducing bacteria (SRB), so this bacterial species was taken as a subject of various scientific studies often.…”
