The Japan Steel Works, Ltd. (JSW) developed the crack growth characteristics used in Fitness-For-Service (FFS) assessment for the old generation 2. 25Cr-1Mo steel heavy wall hydroprocessing reactors with the propagating crack-like flaws. This procedure evaluates the present integrity given by a current state of damage and the projected remaining life of reactor by the applicable FFS Codes. The study of API 579-1⁄ASME FFS-1 Part 9 Assessment of Crack-Like Flaws Level 3 assessment is introduced in this paper.
