In the United States, federal regulations require that jurisdictional pipelines for which the threat of internal corrosion exists be assessed by in-line inspection (ILI), hydrostatic pressure testing, Internal Corrosion Direct Assessment (ICDA) or another method to assure their integrity. Removing the threat of internal corrosion can be justified if sufficient historical data on gas quality, monitoring, and/or inspection exists. A need therefore exists for a technically defensible and systematic process by which the internal corrosion threat can be determined. This paper describes a standard approach to organizing, integrating and analyzing data to identify whether internal corrosion is a threat for a given pipeline segment. A case study illustrating the implementation of the approach is also provided.
