CORROSION— Conclusion: Pitting corrosion models improve integrity management, reliability

07/27/2009
New deterministic and stochastic models for external pitting corrosion in underground pipelines can help improve integrity and reliability analyses. This concluding article applies these models to Monte Carlo-simulated and real pipeline pitting corrosion data obtained from field and in-line inspections (ILI).Part 1 of this series (OGJ, July 20, 2009, p. 64) described a deterministic predictive model relating pit growth to soil and pipeline characteristics, showing it is possible to establish a physically sound correlation between pitting model parameters and soil and pipeline characteristics.Part 1 also described a continuous-time, nonhomogenous linear growth Markov process developed for ...
