Underground pipelines that transport liquid petroleum products and natural gas are critical components of civil infrastructure, so corrosion prevention is an important part of asset protection strategy. Underground Pipeline Corrosion provides a fundamental understanding of the issues associated with corrosion detection and mitigation, as well as the current state of corrosion prevention technology. Part one covers the following topics: basic principles of corrosion in underground pipelines, AC-induced corrosion of underground pipelines, the significance of corrosion in onshore oil and gas pipelines, numerical simulations for cathodic protection of pipelines, and the use of corrosion inhibitors in managing corrosion in underground pipelines. Part two describes several methods for detecting corrosion in underground pipelines, including magnetic flux leakage, close interval potential surveys (CIS/CIPS), Pearson surveys, in-line inspection, and the use of both electrochemical and optical probes. While the emphasis is on pipelines transporting fossil fuels, the concepts also apply to metallic pipes used to deliver water and other liquids. Underground Pipeline Corrosion is a comprehensive resource for corrosion, materials, chemical, petroleum, and civil engineers who build or manage onshore and offshore pipeline assets; professionals from steel and coating companies; and academic researchers and professors interested in corrosion and pipeline engineering.
