Dent in tank shell
Dent in tank shell
(OP)
I have a 35 ft atmospheric tank which shows some dent (inward deformation). Bulge would be a better word but bulge is for outward deformation.
How can I evaluate them for integrity and return in service ? API 579 don't include cylindrical with more than 42 inches diameter...(section 12). Can you help me to find some acceptance criteria ?
Does the fact that dent are inward and tank is only atmospheric pressure (under 16 psi at the bottom)help to not being a big issue here ?
Please discuss

Now, what code or calculation guide can I use to evaluate the damage I have.
Dents are not deep, maybe 1 to 2 inches maximum.

If I have no choice, the FEA will be the solution.
Thanks

Has the tank had product or water in it since the dent's been there?
