A simple question: when are spherical storage tanks used? !

See how much capacity you need; for example, if it’s 5000, then use balls!

1) The spherical tank has the smallest surface area; in other words, for the same capacity, it requires the least amount of steel. 2) The load-bearing capacity of the shell plates of spherical tanks is twice that of cylindrical vessels; that is, at the same diameter and pressure, using the same type of steel sheet, the plate thickness required for a spherical tank is only half that of a cylindrical vessel. 3) Ball tanks require less floor space and can be designed to greater heights, which facilitates the efficient use of available space.

Therefore, compared to vertical cylindrical storage tanks, at the same volume and pressure, spherical tanks have the smallest surface area, which means less steel is required ； 2. The wall panels of spherical tanks are in the shape of a sphere, while those of other types of storage tanks are flat or curved; from the perspective of stress analysis, spherical wall panels are more appropriate. Therefore, at the same diameter, the internal stress in a spherical tank wall is minimal and uniform; its load-bearing capacity is twice that of a cylindrical vessel. As a result, the wall thickness of a spherical tank needs to be only half that of the wall thickness of a corresponding cylindrical vessel. 3. Based on the above characteristics, the use of spherical tanks can significantly reduce steel consumption; generally, 30% to 45% less steel is required (according to incomplete statistics) ； Furthermore, spherical tanks occupy less space and require less foundation work, thus saving land area.

Pressurized storage (up to 6.4 MPa), with a capacity ranging from 50 to tens of thousands of cubic meters, saving materials and space.
