API 650 aboveground steel oil storage tanks internal pressure

Under the action of the earthquake, API 650 storage tank is mainly damaged by the phenomenon of the lower part of the API 650 aboveground steel oil storage tanks tank wall. Therefore, the key point of seismic calculation is to prevent the tank wall from buckling under axial pressure.

The factors that affect the "small breathing" loss of API 650 aboveground steel oil storage tanks are: 1. Generally, the larger the storage tank is, the larger the total open area is, the larger the evaporation area is, and the greater the "small breathing" loss is; conversely, the smaller the storage tank is, the smaller the evaporation area is and the smaller the "small breathing" loss is. 2. It is related to the atmosphere. The lower the atmospheric pressure is, the greater the "small breathing" loss is; otherwise, the loss is reduced.

Large Steel Storage Tank Anchorage
In addition to the loads in API 620 oil storage tank Q.4, Q.5.1, and Q.5.2, the anchorage for the tank that contains liquid, whether it be a single-wall tank or the inner tank of a double-wall tank, shall be designed to meet the requirements of Q.3.6.2 through Q.3.6.5. The anchorage shall accommodate movement of the tank wall and bottom caused by thermal changes. For anchored flat-bottom tanks, the anchorage shall be designed as described in Q.3.6.4.1 through Q.3.6.4.3.
