80ft diameter API Std 650 self-anchored flat-bottom tanks

Above-ground API 650 storage tanks (vertical cylindrical flat-bottomed storage tanks) allow the storage of large volumes of goods at low cost. The only limitation is that they API Std 650 self-anchored flat-bottom tanks can be used under atmospheric pressure or relatively small internal pressure. There are different specifications and standards for the design of API 650 storage tanks.

The normal operation of API Std 650 self-anchored flat-bottom tanks includes receiving oil, storing oil, sending oil and measuring oil. The correct use and operation of oil storage tank is directly related to the production safety and oil loss of oil tank. In order to use and operate the API Std 650 self-anchored flat-bottom tanks correctly, it is necessary to be familiar with and master the structure and performance of the API Std 650 self-anchored flat-bottom tanks and its accessories, such as the maximum storage capacity of the oil tank, the pressure range that can bear and the safety fabrication specification.

API 620 Tank Design
The designer of these large tanks API Std 650 self-anchored flat-bottom 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.
