Large API standard 650 flexible liquid storage tanks
Application scope of API 650 petroleum storage tank:1. API standard 650 flexible liquid storage tanks Working pressure: atmospheric storage tank;2. API 650 petroleum storage tank working temperature: -30℃~150℃;3. API 650 petroleum storage tank liquid medium: various oil products, including naphtha, gasoline, diesel, kerosene, crude oil, fuel oil, heavy oil, benzene, xylene, methanol, ethanol;4. API 650 petroleum storage tank volume: current design considerations generally do not exceed 10,000 cubic meters.
Atmospheric API standard 650 flexible liquid storage tanks refer to storage tanks whose gas or vapor pressure is greater than -0.02MPa but less than 0.1MPa. Metal atmospheric storage tanks made of steel welded on the ground are often used to store petroleum, chemical and other similar liquids. Atmospheric API standard 650 flexible liquid storage tanks usually have a connecting pipe directly connected to the atmosphere, so that the operating pressure in the storage tank does not exceed the design pressure at all times.
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 StressesDesign 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 TankThe 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 StabilityThe 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.
