API 650 aboveground oil storage tanks shell design

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.

Above-ground API 650 storage tanks (vertical cylindrical flat-bottomed storage tanks) allow the storage of large volumes of goods at low cost. The only limitation is that they API 650 aboveground oil storage tanks can be used under atmospheric pressure or relatively small internal pressure. There are different specifications and standards for the design of API 650 storage tanks.

For the welding of API 650 aboveground oil storage tanks bottom, attention should be paid to the slag removal and drying of the welding joint before welding, and there is no sediment and oil contamination in the lap joint of steel plate. The manufacturing quality and production efficiency of the central plate can be obviously improved by adopting the rolling central plate. The butt joint is used between the rolling plates to improve the installation conditions of the central plate at the bottom of the API 650 aboveground oil storage tanks. The welding sequence of the central plate is from the center of the central plate to the surrounding.
