Stress corrosion cracking of natural gas pipelines in low-pH environments is a serious problem for the gas transmission industry. To date, researchers have experienced significant difficulties in reproducing cracking in the laboratory. This paper describes results of an ongoing program investigating crack growth of an API X-65 line pipe steel in a low-pH cracking environment using a J-integral technique. The primary objectives of this research are to reproduce the cracking observed in the field and identify an appropriate crack driving force parameter. Significant crack growth has been observed in the testing and the J-integral appears to be a good parameter for characterizing crack growth behavior.
