Abstract
To use pressurized facilities safely and effectively, a likelihood of failure (LOF) for the brittle fracture was analyzed quantitatively through the risk based inspection using API-581 BRD. We found that for the case of the low temperature/low toughness and the temper embrittlement, the technical module subfactor (TMSF) showed high value for the A impact curve, low temperature, and the no post weld heat treatment. But the risk didn't significantly change at the
압력설비를 안전하고 효율적으로 사용하기 위하여 본 연구에서는 API-581 절차에 의한 위험기반검사에서 취성파괴에 의한 사고발생 가능성을 정량적으로 해석하였다. 그 결과, 낮은 온도/낮은 인성파괴와 뜨임취성에서는 A 충격곡선이고. 낮은 온도와 열처리 전인 상태에서 기술종속계수(TMSF)가 큰 값을 나타내었고,
