This study presents an overview of the corrosion threat to gas and liquid pipelines, focusing on the prevention, detection, characterization, and management of internal and external corrosion, primarily on onshore pipelines. The report provides concise information on the state of pipeline corrosion control, the gaps in current knowledge, and the direction of current research and development. While not formally or comprehensively addressing corrosion of offshore pipelines, this study does highlight aspects of corrosion in offshore pipelines in various sections and is specific in reference when discussed.
