API Std 650 flat-bottom oil storage tanks impact tests
The API Std 650 flat-bottom oil storage tanks outer tank, which is not in contact with the vaporized liquefied gas, may be of single-welded lap or single-welded butt construction when the thickness does not exceed 3/8 in.; at any thickness, the API 620 oil tank outer tank may be of double- welded butt construction without necessarily having full fusion and penetration. Single-welded joints shall be welded from the outside to prevent corrosion and the entrance of moisture.
The API Std 650 flat-bottom oil storage tanks external floating roof tank of API 650 tank has many advantages, and its application range is more and more wide. It is a kind of storage tank with a bright future. The well-designed internal floating roof tank of API 650 tank is the best and least investment method to control evaporation loss of API Std 650 flat-bottom oil storage tanks Fixed roof tank.
Usually, the soil resistance of the foundation should be considered before the design and construction of API Std 650 flat-bottom oil storage tanks. The soil endurance in the API Std 650 flat-bottom oil storage tanks construction area plays a decisive role in the basic cost of the tank. In areas with high soil resistance, not only the cost of foundation treatment can be greatly reduced, but also the ratio of height to diameter of storage tank can be obtained. Therefore, the investment cost of the API Std 650 flat-bottom oil storage tanks can be greatly saved in the area with large soil resistance.
