Description 88-94
A parametric pit design in the outer surface of the oil pipeline buried under the soil atmosphere is investigated. This
study analyzes the effect of pit size and corrosion contours to evaluate the metal degradation due to various characteristics
that impact the corrosion on the oil pipeline. A 3D design of the model has been chosen, and its geometry is modeled in
COMSOL MULTIPHYSICS, and appropriate meshing is done before computing to analyze impact of pit size and electron
current density in oil pipeline. The behaviour of the pit design was then analysed using various parameters such as electron
current density, corrosion rate, the impact of the pit size in localized area. The current findings in the study shows that risk
of metal degradation and the depth of the pit size gives a relationship for corrosion in the localized area and the risk for
pitting corrosion can be reduced by improving pipeline condition monitoring.
