The operating temperature of API standard 650 cylindrical tanks

With the continuous development of large-scale oil storage tanks, the foundation of API standard 650 cylindrical tanks has also continued to grow. Among them, API standard 650 cylindrical tanks vertical oil tanks are storage tanks commonly used to store crude oil, diesel, gasoline and other oil materials. This type of storage tank is set up as a cylindrical shape. The bottom of the tank is a circular flat bottom plate, and the load surface of the oil tank is basically horizontal, which can generally be regarded as a uniform load, and has greater flexibility.

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.

The advantages of API 650 floating roof tanks have obvious environmental and economic benefits: in a specific climate environment, according to historical data, the economic value of the API standard 650 cylindrical tanks floating roof tanks in API 650 due to the reduction of oil and gas volatilization within 3-6 months is equivalent The installation and purchase cost of the API standard 650 cylindrical tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.
