API standard 650 unanchored tanks mixer components

After the API standard 650 unanchored tanks is manufactured, air tightness test and water filling test are carried out according to the design requirements, and the pipeline must be subjected to pressure test to fully meet the acceptance technical specifications. Improve the quality assurance system, adhere to the principle of who constructed is responsible for the quality of the project, conduct regular quality inspections, and immediately rectify any problems. Fill in the API standard 650 unanchored tanks installation technical records in time to ensure the synchronization, integrity and reliability of the technical data.

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.

Welded steel API standard 650 unanchored tanks storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API standard 650 unanchored tanks all adopt on-site production and installation of storage tanks.
