Internal corrosion-monitoring systems have been widely used for over 50 years. In spite of the amount of time these systems have been in use, the true measurement of internal corrosion and atomic hydrogen permeating through steel have often not been obtained. The equipment used to obtain and gather these measurements has often been: installed and then not utilized; installed and utilized, but the data has not been put into use; or worst of all not even installed in the first place. The current intrusive monitoring methods and the first generation of patch-type devices have increased the cost of internal corrosion-monitoring programs. In addition to the increased cost, the true measurement of the actual corrosion and hydrogen flux has continued to evade those who need this data for safe and cost-effective pipeline operations. The more recent development of equipment, Instrumentation, and software for the measurement of corrosion and hydrogen permeation offers an accurate and user-friendly alternative to traditional intrusive monitoring methods. The use of modern PC-based instrumentation, and the use of electronics to both record and store this data, has offered the user for the first time true measurements of actual corrosion and hydrogen flux as it relates to pipeline operations. In this paper the author discusses pipeline failures; corrosion costs; why internal corrosion occurs in pipelines; internal corrosion monitoring methods with a summary of each; and four case histories of actual field data are given showing the relationship of pipeline corrosion and unusual or upset events taking place during the operation of pipelines.
