RE: Corrosion Pitting
What's the nominal plate thickness?
Approximately how much of the shell has this pitting?
If you're still above T-min, you should look into mitigation by coating the shell.
A lot of our gasoline tanks have that GENERAL pitting throughout the entire shell and floor. Usually, it's not bad enough to have to repair, but would be at the next interval. To mitigate, we coat.
