The common API Std 650 self-anchored flat-bottom tanks defects are: Tank cracks, tank welding defects. The cracks on the base metal, surface and near surface of the tank wall shall be eliminated by grinding with circular arc, and then magnetic particle inspection or re inspection shall be carried out. Cracks in heat affected zone: generally, grinding method is used to eliminate cracks, and magnetic particle or dye flaw detection is used to confirm that there is no crack, and then repair welding or grinding smooth transition.

The increased uplift described in API Standard 620 tank Appendix Q is intended to apply to the size of the ringwall and foundation but not the anchorage. For tanks with an internal design pressure of 1 lbf/in.2 gauge and over, the uplift, if any, shall be calculated under the combined conditions of 1.25 times the internal design condition plus the design wind load on the API Std 650 self-anchored flat-bottom tanks shell and roof.
