Pipelines are a very safe and cost-effective way of transporting fluids under pressure. However, as with any metallic structure, they can develop flaws that cause the structure to rupture or leak. To prevent this, several researchers and organizations have attempted to develop models that can compute the severity of pipeline defects. In order to better exploit and apply these various models, we have developed in this article a parametric study based on the most commonly used analytical models in the industry. The parametric study considers the crack’s size and location, as well as the internal pressure of the tube. The findings of this study shed light on the most important parameters for each model under consideration.
