API Std 650 mechanically-anchored tanks top-angle attachment for self-supporting roofs

Usually, the soil resistance of the foundation should be considered before the design and construction of API Std 650 mechanically-anchored tanks. The soil endurance in the API Std 650 mechanically-anchored tanks construction area plays a decisive role in the basic cost of the tank. In areas with high soil resistance, not only the cost of foundation treatment can be greatly reduced, but also the ratio of height to diameter of storage tank can be obtained. Therefore, the investment cost of the API Std 650 mechanically-anchored tanks can be greatly saved in the area with large soil resistance.

The API Std 650 mechanically-anchored tanks outer wall shall be designed for the purging and operating pressure of the space between the inner and outer tank shells and for the loading from the insulation, the pressure of wind forces, and the roof loading.
The outer tank bottom, shell, and roof shall have a minimum nominal thickness of 3/16 in. (7.65 lbf/ft2) and shall conform to the material requirements of Q.2.3.

The temperature requirements of the API 650 oil storage tank area are closely related to the evaporation loss, energy loss, API Std 650 mechanically-anchored tanks storage and storage platform tank materials and the selection of detection instruments, or the temperature of the API 650 oil storage tank area. The cost of storage has a direct impact.
