Abstract	Corrosion defects may compromise the safety of oil and gas pipelines. Researchers studied the failure behavior and failure pressure of X80 pipelines with longitudinally and circumferentially aligned interacting corrosion defects based on nonlinear finite element method. X80 pipeline with single corrosion defect was examined, as well. Based on proposed failure pressure regression equations for X80 pipeline with single corrosion defect, researchers developed an assessment procedure for predicting failure pressure of pipeline with interacting corrosion defects.
