Abstract: The traditional two-curve crack arrest control model based on Charpy impact toughness is no longer suitable for the high-grade steel pipelines, which poses a great threat to the safety of energy transportation. The Crack Tip Opening Angle (CTOA), as a promising crack arrest toughness parameter, is expected to replace the Charpy impact toughness and form a new crack arrest control method. However, there has been no adequate progress and verification in the relevant research by now. Therefore, the latest research progress home and abroad was comprehensively reviewed and discussed from three aspects, which are the standard test of CTOA with laboratory specimens, the transferability of CTOA test results, and the CTOA based crack arrest control method. Meanwhile, the disputes and deficiencies in the current research were pointed out, and the future working direction of the researches was analyzed. It is expected to promote the research process in the field of crack arrest control of pipelines, as well as the development of pipeline construction in China.
