API standard 650 petroleum storage tanks material

API 650 external floating roof storage tanks are generally called external floating roof API standard 650 petroleum storage tanks tanks, which means that the storage tanks are externally open tanks without a dome design, and are equipped with vertical floating roofs. API 650 external floating roof storage tanks are usually used for large More than 20,000 cubic meters of open steel API standard 650 petroleum storage tanks storage tanks for storing volatile petroleum products such as crude oil, gasoline, kerosene, etc.

The main reason of "small breathing" loss of API standard 650 petroleum storage tanks is the change of atmospheric temperature. When the temperature rises with the increase of solar radiation from dawn, the temperature of oil in the API standard 650 petroleum storage tanks also changes, resulting in the acceleration of evaporation speed and the increase of evaporation pressure. When the pressure exceeds the positive pressure rating of the breathing valve, the oil-gas mixture in the API standard 650 petroleum storage tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil 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.
