An Efficient Methodology for the Reliability Analysis of Corroding PipelinesSource: Journal of Pressure Vessel Technology:;2014:;volume( 136 ):;issue: 004::page 41701DOI: 10.1115/1.4026797Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes an efficient methodology that utilizes the first order reliability method (FORM) and system reliability approaches to evaluate the timedependent failure probabilities of a pressurized pipeline at a single active corrosion defect considering three different failure modes, i.e., small leak, large leak, and rupture. The criteria for distinguishing small leak, large leak, and rupture at a given corrosion defect are established based on the information in the literature. The wedge integral and probability weighting factor methods are used to evaluate the probabilities of small leak and burst, whereas the conditional reliability index method is used to evaluate the probabilities of large leak and rupture. Two numerical examples are used to illustrate the accuracy, efficiency and robustness of the proposed methodology. The proposed methodology can be used to facilitate reliabilitybased corrosion management programs for energy pipelines.
