SEM/EDS analysis of corrosion products from the interior of a crude oil pipeline

Within the framework of environmental protection, internal corrosion risk assessment is one of the most important activities of modern pipeline corrosion management. In order to assess the risk of internal corrosion of pipelines, it is important to understand corrosion mechanisms and be able to predict whether localised corrosion will be initiated and how it can be prevented. In the present work we investigated corrosion products from the interior of the of carbon steel crude oil pipeline sampled at a low-lying dead-leg where wall perforation due to corrosion has already occurred. Morphological and compositional studies were conducted by SEM-EDS and microbiological analysis was done by using growth assay. Application of a combination of the two complementary analytical techniques enabled root cause analysis revealing a pattern specific to the corrosive action of biotic corrosive media and indicating bacterial activity and scale formation as the main root cause of the observed corrosion failure.
