API standard 650 liquid-storage tanks bottom-transition plate
Design calculations and drawings required API standard 650 liquid-storage tanks for the fabrication and erection of each API 650 tank. A drawing index for each API 650 tank is required and shall be re-submitted each time drawings are revised and re-issued.
API standard 650 liquid-storage tanks any joints between the adjacent sections of stiffening rings, as shown in Figure R-1, shall be made so that the required moment of inertia of the combined ring-shell section is provided. Weld joints between adjacent sections shall be made with full-thickness and full-penetration butt-welds. Stiffening-ring butt-welds may employ metal backing strips. Backing strips and the associated welding shall be made in a manner that provides a smooth contour in the rat hole and all other weld joints ends. All weld passes shall be started at the rat hole.
The foundation design of the API standard 650 liquid-storage tanks should meet the requirements of foundation stability and deformation, that is, the API standard 650 liquid-storage tanks foundation should not be crushed and the uneven settlement value of the foundation should be within the allowable range. The uneven settlement of the storage tank foundation should be specified in the design process of the safe allowable range, because excessive uneven settlement will reduce the safety of the API standard 650 liquid-storage tanks and cause distortion and deformation of the tank wall and bottom plate.
