API standard 650 cylindrical tanks level gauge

The interior of API 650 storage tanks to be internally lined or coated must have all edges rounded to a minimum of 3 mm radius. Internal welds must be completely seal welded, ground smooth, and free from API standard 650 cylindrical tanks surface porosity, pockets, and high spots. Remove weld spatter. Vendor as specified on API 650 storage tanks drawing must perform additional surface preparation.

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.
