Factors that cause stress-corrosion cracking in buried pipelines appear to be a sodium carbonate/sodium bicarbonate environment, a critical electrochemical potential, and a stress above the threshold stress of the steel. Other factors that contribute to the cause are coating defects, elevated temperatures, and pressure fluctuations. Promising preventive measures that are still under investigation are the use of more resistant line-pipe steels and control of the potential through modifications in cathodic-protection practices. This study reviews the nature of stress-corrosion cracking of pipelines and the progress of research to date, with some comments about promising ongoing activities.
