RELIABILITY OF UNDERGROUND PIPELINES SUBJECT TO CORROSION

The reliability of underground pipelines can be determined by external loading and corrosion, which can occur internally or externally. Corrosion affects pipeline strength in resisting applied loads, which impacts on reliability over time. Through probabilistic modeling of the pipe wall material loss, corrosion can be viewed as a nonlinear function of time. The probability of system failure is evaluated using techniques developed for structural reliability analysis. From a numerical investigation of an example pipeline, researchers found that there is a very significant long-term contribution of the corrosion parameters to structural reliability deterioration, and that this is directly related to the corrosion parameters.
