摘要

The effect of longitudinal bending moment in pipeline with a wall thinning defect of large overall size in circumferential direction on the risk of failure is considered. It is shown that the critical sizes of thinning in circumferential direction can be determined with a certain conservatism on the basis of total nominal stresses induced by bending and internal pressure in pipeline.
