The aim of the present work was to construct safety diagrams based on the finite element analysis of corrosion defect in buried pipelines. The numerical simulation was performed using the real defect geometry and three simplified defect geometries. Burst tests have been carried out on several pipe sections, in order to verify the finite-element calculation results.
