What is Microbial Corrosion in API 5L X52 Pipeline about?

- The premature failure of an 18-inch API 5L X52 crude oil trunkline after less than 2 years of operation was investigated. - Visual examination and metallographic analysis revealed severe localized corrosion in the form of deep pits, particularly around the circumferential weld seam. - Microbiological analysis detected the presence of sulfate-reducing bacteria, indicating microbial-influenced corrosion was the primary cause of failure. The pipeline likely became contaminated during its hydrotest with unt
