Abstract

The use of Carbon Steel is conventional for the transmission and distribution of treated Natural Gas. In order to control the internal corrosion of the gas transfer Pipelines, the moisture content is removed in dehydration unit. In addition, the amount of CO2 gas is limited to less than 2%. In this study, the cause of the failure of an 8-inch gas distribution Pipeline is investigated. The Pipeline was not in service for two years and then it was in operation for 6 years before the failure. Microscopic examinations, as well as chemical analyzes such as EDS and XRD, were used to determine the possible mechanisms of damage. In addition, the NORSOK CO2 Corrosion model was used to determine the corrosion rate in operating conditions. The results showed that corrosion caused by carbon dioxide is the most likely cause of internal corrosion of the Pipeline and the occurrence of the leakage.
