A Risk Assessment Method of Corroding oil Pipelines

The risk assessment method on corroded oil pipeline failure with analytic solution is introduced in detail. On the basis of ASME B31G and DNV, a calculation model on failure probability of corroded pipeline is established. Combining the statistical data of pipeline accidents abroad, the consequence assessment model is set up by applying Bernoulli equation. In this paper, the method to establish acceptable standard of risk is described.
