Basic requirements for large-scale API 650 aluminum tanks basic design

Large-scale API 650 aluminum tanks is characterized by large diameter and heavy load, so it has special requirements for foundation and foundation design. Generally speaking, large-scale API 650 aluminum tanks structures are thin-walled container structures welded by steel plates, which have the characteristics of large flexibility and low rigidity, so they can withstand the foundation settlement deformation that ordinary buildings cannot withstand. Even if the foundation of some API 650 aluminum tanks has subsidence, as long as the settlement is uniform, it still does not affect the use of API 650 aluminum tanks.

Because API 650 aluminum tanks has a large diameter and low height "short and fat" structure, the impact of wind is very small, and it only moves when a typhoon or an empty tank occurs. Therefore, when building large-scale API 650 aluminum tanks in areas where the wind level is greater than 10, full consideration should be given to the anchoring of API 650 aluminum tanks and the foundation. When designing a large-scale API 650 aluminum tanks foundation, the following requirements should be considered:

First of all, it is necessary to consider that the foundation should meet the total load of the large API 650 aluminum tanks's own weight and the test water weight. If it cannot be satisfied, an appropriate foundation treatment method must be selected to treat the foundation, which has reached the API 650 aluminum tanks requirements for foundation bearing capacity. Secondly, we must pay attention to the settlement and deformation of the foundation. The total settlement and uneven settlement of the API 650 aluminum tanks foundation must meet the basic requirements of API 650 aluminum tanks allowable settlement and inclination, and sometimes may exceed the basic allowable value, but it does not affect the normal use of API 650 aluminum tanks.
