Debunking the API 653 Corrosion Rate Estimation

[@storagetanktraining5863]

This video was brought to my attention so I watched it and for what it's worth, have this to offer. 1st, API 653 was and is a great standard, but on several issues, it can be challenged and this is one of those areas of contention. 2nd, Mr. Myers is correct in that, depending simply on what side of the bottom plate the “same depth of pit” is located, that a person may calculate differing results in futuristic useability of the existing bottom plate. 3rd, I may slightly disagree with the assertion that topside and underside corrosion will not be located directly opposite to one other. Some believe that the possibility for alignment increases as the tank’s diameter decreases. (That’s another discussion) 4th, I would never pick an intellectual argument with Mr. Myers. Thank you.

The corrosion rate calculations definitely should be updated and revised with more clear language and not combining internal and external corrosion rates (assuming they line up).
