40ft diameter API standard 650 ground supported liquid storage tanks

In Appendix E to API 650 oil storage tank, the maximum values of inertia force, pulse pressure and convection pressure are superimposed, and tend to be conservative.In GB50341, only pulse pressure is calculated for API standard 650 ground supported liquid storage tanks tanks below 5000 m.

The main advantages of the external floating roof API standard 650 ground supported liquid storage tanks are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API standard 650 ground supported liquid storage tanks, the production of external floating roof API standard 650 ground supported liquid storage tanks is simple and the steel consumption is less. However, the central drainage system of external floating roof API standard 650 ground supported liquid storage tanks should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.

Insulation Load
For API 620 tanks designed and constructed with an outer tank containing loose fill insulation in the annular space between the tanks, the insulation weight shall be divided equally to the inner and outer tank wall for seismic lateral loads unless a more rigorous analysis is performed to determine the distribution. The insulation within the annular space shall not be used to calculate resistance to overturning. Insulation on the API standard 650 ground supported liquid storage tanks roof or suspended deck shall be applied to the tank supporting the load at the point or center of gravity of attachment and may be used to resist overturning.
