The diameter of API Std 650 unanchored flat-bottom tank

API 650 tank has the advantages of less load on the floating plate, simple and light structure, and can save the central drainage pipe and rotating floating ladder on the API Std 650 unanchored flat-bottom tank floating plate. The materials for easy construction and maintenance and sealing parts can avoid aging due to sunlight.

Anti corrosion of API Std 650 unanchored flat-bottom tank:
After using for a certain period of time, it is necessary to check the corrosion protection of the API Std 650 unanchored flat-bottom tank. If necessary, the outer wall of the metal oil tank should be painted with new anti-corrosion paint to ensure that the outer wall of the API Std 650 unanchored flat-bottom tank does not fall off and has good waterproof and rust resistance.
API Std 650 unanchored flat-bottom tank cleaning:
The long-term use of API Std 650 unanchored flat-bottom tank will produce impurities on the tank wall and deposit on the tank bottom, resulting in tank corrosion to leakage. According to the safety standard of oil tank, the API Std 650 unanchored flat-bottom tank shall be cleaned and derusted regularly to ensure the quality of oil stored and the safety of oil tank equipment.

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.
