CSA G40.21 grade 350W plates API 650 flexible liquid storage tanks

The engineering quality of API 650 flexible liquid storage tanks not only affects production and operation, but also affects the life safety of the staff. The factors affecting the API 650 flexible liquid storage tanks construction quality are all aspects, any link, any part of the problem will affect the whole project, so the quality management is paid more and more attention. How to ensure the engineering construction quality of oil tank? First, make API 650 flexible liquid storage tanks construction technical preparation carefully, understand the design intent, master the construction acceptance specification, and make detailed construction technical disclosure to the construction team.

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.

Under the action of the earthquake, API 650 storage tank is mainly damaged by the phenomenon of the lower part of the API 650 flexible liquid storage tanks tank wall. Therefore, the key point of seismic calculation is to prevent the tank wall from buckling under axial pressure.
