API 650 aboveground welded storage tanks leg sleeves

Strictly controlling the temperature in the API 650 aboveground welded storage tanks can effectively reduce the volatile consumption of oil in large oil storage tanks. Because the higher the temperature in the oil storage tank, the stronger the activity of oil molecules and the greater the volatilization consumption of the oil. Therefore, the temperature in the API 650 aboveground welded storage tanks must be reduced as much as possible. It is possible to reduce the direct sunlight temperature by painting white anticorrosive paint with good light reflectivity. It is also possible to use spray equipment to wash the top and wall of the API 650 aboveground welded storage tanks with water flow to reduce the volatilization consumption of the oil in the storage tank.

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.

API 650 "welded storage tanks" API 650 aboveground welded storage tanks is a standard developed and issued by the American Petroleum Institute (API), which specifies the minimum requirements for the design, manufacture, installation and inspection of welded storage tanks.
