Software System for Automating Internal Corrosion Direct Assessment of Pipelines

Abstract Assessment of internal corrosion of pipelines is a complex task, requiring integration of substantial scientific and engineering analyses in multiple disciplines, including thermodynamics, electro-chemistry, fluid dynamics and metallurgy. The authors, over the last ten years, have developed a widely used corrosion prediction model to predict corrosion in aqueous systems. This software system has been extended to corrosion prediction and assessment in pipelines, and provides a rigorous framework to characterize corrosion of pipelines from a stand point of water phase behavior, speciation and fluid dynamic parameters en route to assessment of critical angle for water hold up, and a basis to assess severity of Internal Corrosion. The system promotes both accurate and fast evaluation of pipeline systems in a moderately hilly terrain, and provides a rigorous framework to determine the health of pipeline systems and identify critical locations for corrosion monitoring and inspection.
