5052 aluminum shapes API standard 650 carbon steel tank

Soil Structure Interaction: Soil structure interaction per API 650, Section E.6.1.6 may be used for OLE design providing the damping ratio does not exceed 10 %.
Allowable Stresses
Design allowable stresses shall be per API 620 large welded steel storage tank, Section Q.3.3, including the 33 % increase permitted for earthquake loads.
Self-anchored Inner Tank
The anchorage ratio for a self-anchored inner tank, J, shall not exceed 1.0 for the OLE design combination to limit uplift and stresses in the annular plate and corner weld.
Foundation Stability
The overturning ratio defined in API 650, Section E.6.2.3, Equation (E.6.2.3-1) shall be equal to or greater than 3.0 for the defined OLE event.

This standard only applies to API 650 storage tanks API standard 650 carbon steel tank with uniform bottom support and non-refrigerated service storage tanks with a maximum design temperature of not more than 93 degrees Celsius (200 degrees Fahrenheit).

Generally, the building area temperature of the API standard 650 carbon steel tank should be considered before the tank design and construction. The temperature in the API standard 650 carbon steel tank building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the API standard 650 carbon steel tank, the higher the corresponding pressure and the more volatile loss.
