A573 grade 450 plates API standard 650 carbon steel tank

Under the same sealing effect, the internal floating roof tank of API 650 oil storage tank can further reduce the evaporation loss compared with the API standard 650 carbon steel tank External floating roof tank. This is due to the shielding of the fixed roof and the gas layer between the fixed roof and the internal floating plate, which has more significant heat insulation effect than the double disc floating roof of the API standard 650 carbon steel tank external floating roof tank.

The foundation design of the API standard 650 carbon steel tank should meet the requirements of foundation stability and deformation, that is, the API standard 650 carbon steel tank foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the API standard 650 carbon steel tank and cause distortion and deformation of the tank wall and bottom plate.

Storage Tank Annular Bottom Plates
Thickness shall be per API 650, Appendix E (with loads modified by requirements of this appendix) plus corrosion allowance unless a thickness increase is required for compliance with Appendix R or Appendix Q. Annular plate width shall be per API 650, Appendix E (with loads modified by requirements of this appendix) unless a width increase is required for compliance with Appendix R or Appendix Q. Thickness used for determination of API 650 welded storage tank standard, Appendix E width shall be based on the thickness required for seismic product hold down.
