Burst capacity and development of interaction rules for pipelines considering radial interacting corrosion defects

Pipelines failures during its service life caused by the impact of multiple corrosion defects are most probable to occur, which may induce severe consequences as compared to single defect acting alone. Interaction rules were developed for multiple defects in the longitudinal and circumferential dire...
