CSA G40.21 Gr 300W plates API Std 650 unanchored liquid-storage tanks

API 650 stipulates that an open tank should be provided with a wind-resistant ring to ensure that the API Std 650 unanchored liquid-storage tanks tank body maintains its roundness when subjected to wind. There are no hard and fast rules for vault API 650 storage tanks. It can be determined by comparing the equivalent wall height with the maximum height of the unreinforced tank wall.

The water dissolved in the oil will be separated out from the oil stored in the API Std 650 unanchored liquid-storage tanks for a long time, and the acidic water layer will appear at the bottom of the API Std 650 unanchored liquid-storage tanks for a long time, which will accelerate the corrosion of the API Std 650 unanchored liquid-storage tanks and cause the wall thinning and even leakage. With the increase of service life, the API Std 650 unanchored liquid-storage tanks must be inspected and cleaned regularly to check the hidden danger.

Any joints between the adjacent sections of API 620 oil storage tank stiffening rings, as shown in Figure Q-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 joint ends. All weld passes shall be started at the rat hole and other weld joint ends and shall be completed by moving away from these ends. Passes shall be overlapped away from edges to provide a smooth continuous weld.
