1060 aluminum plate API Std 650 self-anchored storage tanks

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.

API 650 Application As described by the American Petroleum Institute, the fabrication and installation of our surface welded API Std 650 self-anchored storage tanks steel storage tanks is normally used in industrial applications. In general, our standards for industrial on-site installation of storage tanks are established according to API 650, API 620 and API 12D.

To scientifically evaluate the remaining service life of the API Std 650 self-anchored storage tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API Std 650 self-anchored storage tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API Std 650 self-anchored storage tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
