| Abstract: |
| This paper described the characteristics of the marine mudflat environment and its difference from submarine mud, and analyzed the occurrence of microbiologically influenced corrosion in this environment. Microbiologically influenced corrosion was considered as one of the most aggressive factors in nature, which was also one of the most important factors causing pipelines failure. This paper introduced the research trends of pipeline corrosion caused by microbiologically influenced corrosion in detail, especially about SRB. It mainly focused on the influence of SRB on hydrogen penetration, failure coatings, local corrosion at defects and cathodic protection. At the same time, the sudden failure of magnesium anodes in the current mudflat environment and the serious corrosion of SRB on magnesium anodes and other materials was summarized and analyzed. The influence and research prospect of SRB existing on magnesium alloys in the mudflat environment was proposed. According to the special mudflat environment, it was particularly important to carry out the research on the influence of SRB on magnesium anode performance, which was even important about the safe operation of oil and gas pipelines. |
