Article Preview

This paper presents the determining method of impact toughness of drill pipe steel used in critical sour environment. Leak-Before-Break fracture principle was adopted to deduce the requirement of drill pipe with different strength grades for impact toughness, which considered both factors, such as geometry size and curvature effect. The loss law of impact toughness was also experimentally measured which could act as a good supplement for Leak-Before-Break fracture principle. Statistical data revealed that this requirement of drill pipe steel for impact toughness could be fully realized through current industrial ability.
