Nominal diameter of API 650 cylindrical welded storage tanks

The tank wall design of API 650 oil storage tank. Since there is no ventilation pipe directly connected with the outside on the top of the API 650 cylindrical welded storage tanks tank, the ventilation between the inside and outside of API 650 oil storage tank is realized by the respiration valve. The constant pressure of the respiration valve is 0.3kPa, so the pressure on the top of the tank is 0.3kPa.

API 620 Tank Design
The designer of these large tanks API 650 cylindrical welded storage tanks shall supply the data on superimposed loadings to be assumed for the foundation design or, if there are no foundations, for direct loading on the subgrade. A slab or mat may be provided to support the superstructure and shall be considered to distribute the load more evenly over a lower natural subgrade compared with merely stripping, leveling, and rolling the existing grade.
For simple spheroids or tanks of similar design, in which the distribution of the imposed weights shifts because the liquid level in combination with the vapor pressure may change the shape of the tank, the designer shall consider the possibility of such a change.

The factors that affect the "small breathing" loss of API 650 cylindrical welded 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.

On November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children.
