Failure assessment of X80 pipeline with interacting corrosion defects

Corrosion defects may compromise the safety of oil and gas pipelines. This paper investigates 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 is studied as well. On the basis of proposed failure pressure regression equations for X80 pipeline with single corrosion defect,...
