Burst pressure prediction of multiple cracks in pipelines

Available industrial code such as ASME B1G, modified ASME B1G and DNV RP- F101 to assess pipeline defects appear more conservative for multiple crack like- defects than single crack-like defects. Thus, this paper presents burst pressure prediction of pipe with multiple cracks like defects. A finite...
