Underground corrosion of pipelines is best controlled by taking advantage of the synergistic effects that are developed when protective coatings are used in conjunction with cathodic protection. When these techniques are not used during pipe installation, or the corrosion control system deteriorates with age, leaks and failures result. These failures require maintenance, which involves economic analysis of repair or replace options. This report discusses the development of several new techniques for assessing and predicting the status of underground pipe corrosion. The polarization decay principle is a nondestructive technique which can determine corrosion status without having to dig up the pipe. The Corrosion Status Index Prediction Reports show quantification and prediction of corrosion damage. Concepts for computerized and manual corrosion management systems have been developed which will enable the Facilities Engineer to determine the most cost-effective options for repairing or replacing damaged pipe.
