Failure analysis of a welded steel pipe at Kullar fault

Jan 01,2017·The failure process begins with wrinkle initiation,followed by wrinkle growth (e.g.,5% internal diameter loss),folding of pipe at the wrinkled area and ultimately rupture of the pipe wall.However,for the performance goal of post-event operability,the literature suggests using the onset of wrinkling as the appropriate limit state.Failure analysis of oil and gas transmission pipelines Jan 01,2016·Data from 2011 show that material and weld failures constitute the largest incident type for both hazardous liquid and gas transmission systems (Figures 1.2 and 1.3).Other authors have indicated that third party damage is the most common cause of incidents in gas transmission systems [].The following sections outline specific pipeline failure mechanisms and provide examples toGas Pipeline Failure Caused by In-Service Welding In the research presented in this paper,a failure analysis had been carried out to identify causes of an incident,which had taken place after an operation to repair a leak in an interstate natural gas pipeline.In this operation,a partial encirclement reinforcement (patch) was welded to the carrier pipe according to an available hot taping procedure,while gas was flowing in the pipeline.
