pitting on carbon steel
(OP)
Is pitting in wet gas carbon-steel pipeline typically a result of passivated film breakdown or other mechanisms? E.g., condensate oil/water wet, under-deposit attack, bacteria?

RE: pitting on carbon steel
"Oxygen pitting" is probably the most common cause. It occurs in low-O2 areas where the rest of the pipe has higher O2.

Low pH usually causes wastage/thinning/general attack rather than pitting.

RE: pitting on carbon steel
Do I assume that if someone likes to do a model on pitting of carbon steel, he has to go through all these factors? It is very complicated. Besides, how statistics will affect the pit distribution?
Why pits have different shapes? Can we tell from the pit shape what kind of corrosion?
