Strain capacity prediction for strain-based pipeline designs

This paper is aimed at comparing the ExxonMobil and UGent predictive tensile strain capacity equations developed in 2011. In addition, the potential issues in their application are discussed. The equations, within their limits of applicability, provide very similar predictions. However, using large scale test results, one can remove the conservatism. It is concluded that Curved Wide Plate testing could be a better and effective means to estimate the strain capacity of flawed pipeline girth welds.
