How to limit evaporation of liquid contents from API 650 self-anchored flat-bottom steel tanks
Lateral braces between outer bay rafters must be provided if asymmetrical structural shapes are used for rafters and if the API 650 self-anchored flat-bottom steel tanks API 650 tanks are located in areas subject to earthquakes. The bracing must be adequately sized for the seismic zone specified.
In this project, an area of steel storage oil tank wall is constructed of ASTM A285, Grade C, steel plate that is 5/8-in. thick and has spot-radiographed, double-welded butt joints. The wall is subject to tension in a meridional direction and to compression in a latitudinal direction. The values of R1 and R2 at the point under consideration are 75 in. and 300 in. respectively. A corrosion allowance of 1/16 in. is required. The computed (meridional) tensile stress, stc, in the net thickness after deduction of the corrosion allowance is 6000 lbf/in.2.
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 self-anchored flat-bottom steel 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.
