Soil-structure interaction effects for API 650 mechanically-anchored flat-bottom tanks

The Charpy V-notch test shall be used, and the minimum impact value at the design metal temperature shall be as given in Table R-2. For subsize specimen acceptance criteria, see ASTM A20. An impact test temperature lower than the design metal temperature may be used by the API 620 welded storage tanks Manufacturer, but in such a case the impact values at the test temperature must comply with Table R-2.

Fixed roof API 650 oil storage tank includes inner floating roof tank, which API 650 mechanically-anchored flat-bottom tanks can effectively prevent sand, rain, snow or dust from polluting the storage liquid. Under various weather conditions, API 650 oil storage tank can ensure the quality of liquid storage, which is called "all-weather API 650 mechanically-anchored flat-bottom tanks storage tank".

With the continuous development of large-scale oil storage tanks, the foundation of API 650 mechanically-anchored flat-bottom tanks has also continued to grow. Among them, API 650 mechanically-anchored flat-bottom 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.
