depth can be predicted after finding out a statistical law describing many samples of pitting …

Probability distribution of pitting corrosion depth and rate in underground pipelines: A Monte Carlo study

F Caleyo, JC Velázquez, A Valor, JM Hallen - Corrosion Science, 2009 - Elsevier
The probability distributions of external-corrosion pit depth and pit growth rate were
investigated in underground pipelines using Monte Carlo simulations. The study combines a …

Predictive model for pitting corrosion in buried oil and gas pipelines

JC Velázquez, F Caleyo, A Valor, JM Hallen - Corrosion, 2009 - meridian.allenpress.com

free from deformation or residual stress on X-52 pipeline steel samples. Pits have been …

A new approach to predict the pit depth extreme value of a localized corrosion process

D Najjar, M Bigerelle, C Lefebvre, A Iost - ISIJ international, 2003 - jstage.jst.go.jp
Depth of pits that propagate during a pitting corrosion process is an important characteristic
of the damage of steels; the greater the depth, the more dramatic the damage. For evident …
