API Std 650 anchored tanks inlet diffusers

API 650 internal floating roof oil tank is a volatile liquid storage tank with a combination of a dome tank and an internal floating roof structure, which is a floating roof assembled under the dome of the API Std 650 anchored tanks storage tank. The combination of the vault roof outside the API 650 storage tank and the floating roof inside the tank has been widely used in gasoline, aviation kerosene and more volatile chemical liquids.

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.

Oil tank is often used to store crude oil, diesel oil, gasoline and other oil. The main structure of API Std 650 anchored tanks is composed of tank top, tank wall, tank bottom and accessories. The API Std 650 anchored tanks should be inspected after the completion of construction, and the detection methods of different structure positions are different. Tank wall inspection: for the newly built oil tank, water filling test shall be conducted to check whether the tank wall is tight, and the appearance inspection shall be conducted for the tank wall plate and weld. Tank wall thickness detection: the oil tank wall thickness is mainly detected by ultrasonic wave, with high efficiency.
