API Std 650 duplex stainless steel tanks leg lengths

The seal of floating roof API Std 650 duplex stainless steel tanks is a device used to reduce the evaporation loss of the storage liquid in the annular space between the tank wall and the outer ring plate of the floating roof. The common sealing forms include mechanical seal, elastic filling seal, lip seal and secondary seal. No matter what kind of seal, the seal must be combined with the floating roof effectively to reduce the evaporation loss of the liquid in the floating roof.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.Pipeline transportation of API 650 oil tank is not less than the maximum consumption of 3 to 5 days.
