5454 aluminum plate API 650 welded tanks for oil storage

Atmospheric API 650 welded tanks for oil storage refer to storage tanks whose gas or vapor pressure is greater than -0.02MPa but less than 0.1MPa. Metal atmospheric storage tanks made of steel welded on the ground are often used to store petroleum, chemical and other similar liquids. Atmospheric API 650 welded tanks for oil storage usually have a connecting pipe directly connected to the atmosphere, so that the operating pressure in the storage tank does not exceed the design pressure at all times.

API 620 Tank Design
The designer of these large tanks API 650 welded tanks for oil storage 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.

Welded steel API 650 welded tanks for oil storage storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API 650 welded tanks for oil storage all adopt on-site production and installation of storage tanks.
