In order to establish a life assessment method for the welded modified 9Cr-1Mo steel hot reheat piping, an internal-pressure creep test was conducted with a full-size test component. As a result, the fracture mode of the component was clarified and the life prediction method was established. Furthermore, creep damage detection procedures are proposed.
