The goal of this compilation is to educate the reader through experiences and observations from real-world applications and to provide tools for the identification and remediation of pipeline corrosion issues before failure. Pipelines have been used to transport fuels since the 19th century. While it is difficult to find a clear consensus of the total number of pipeline miles in use throughout the world, most agree that the U.S. has greater than 2.5 million miles of energy pipelines.
Protection of pipelines begins with appropriate material selection and extends by internal and external coatings, corrosion inhibitors, and cathodic protection. These tools are often used alone or in various combinations to extend the lifetime of a pipeline for decades. Unfortunately, even with a protected pipeline, external and/or unexpected influences, often localized in nature, can degrade the protection and leave the pipeline susceptible to corrosion and potential failure. For this reason, even the most well-protected pipelines must undergo regular inspection to ensure against failures.
The papers included in this compilation explore microbiologically induced corrosion (MIC), corrosion under insulation (CUI), corrosion monitoring techniques, and a variety of additional topics relevant to pipeline corrosion. Studies describe the effects of flow, soil or water composition, monitoring frequency, and material selection. Inspection tools and protocols are also described, allowing for greater insight into how corrosion issues can be identified and controlled throughout the service lifetime. Each of these papers details studies of active pipelines, enabling the reader to learn from actual and often complex circumstances.
