Evaluation methods of leak and collapse loads using material properties were developed for pipes th multiple circumferential flaws. We performed quasi-static four-point bending tests on Type 304 stainless steel pipes th single, double or triple circumferential flaws. In these examinatioos, peak loads were measured at the flaw penetration and the crack propagition from penetrated flaw. Evaluation methods of leak and collapse loads for pipes th the single flaw led to evaluation methods for pipe with multiple circumferential flaws. Evaluation results using material properties obtained by the pipe specimen show in good agreement with experimental resultx
