A841 grade A class 1 plates API 650 flat-bottom oil storage tanks
The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the API 650 flat-bottom oil storage tanks tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.
Storage tank is used to store all kinds of liquid, solid and gas materials. The common types of storage tank are oil tank, water storage tank, chemical tank, cement tank, API 650 flat-bottom oil storage tanks, etc. When choosing the storage tank, users should choose according to their actual needs, such as the material, pressure, form, capacity, temperature, density, etc. In addition, the environmental factors such as the temperature of the tank construction area, the ground endurance of the foundation, and the wind force should be considered.
Allowable Design StressesThe maximum allowable design stresses for the API 650 flat-bottom oil storage tanks materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.
