Abstract:
Pipelines are the cheapest and safest way to transfer fluids in industry. The operation of pipelines, on the other hand, raises the risk of failures such as internal and exterior corrosion, cracking, and warping. It should be noted that non-destructive testing guarantees the correct operation of pipelines before and after failures. As a result, when damage occurs, it is important to fix it in order to avoid loss of life and material. In our study, we generated an external fracture in a pipeline by using the API X80M as the construction material. We then performed a comparative numerical analysis using the ANSYS software, simulating two methods of repair, the first using a half-shell and the second using a composite patch (epoxy carbon). The Von Mises stresses and stress intensity variables were really the parameters considered in our investigation.
