ASTM A181 forgings API standard 650 aboveground petroleum storage tanks
API 650 petroleum storage tank has the advantage of long economic life: because there is no gas space on the liquid surface in the internal floating roof API standard 650 aboveground petroleum storage tanks storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.
The {keyword shell that contains the liquid shall have butt-welded annular bottom plates with a radial width that provides at least 24 in. between the inside of the shell and any lap-welded joint in the remainder of the bottom and at least a 2-in. projection outside the shell. The stated values apply to full-sized specimens. For sub-size specimen acceptance criteria, see ASTM A20. An impact test temperature lower than the design metal temperature may be used by the API 620 large welded, low pressure storage tanks Manufacturer.
According to the standard of head of API standard 650 aboveground petroleum storage tanks, there should be no crack, delamination, inclusion and other defects on the groove surface, which is consistent with the steel plate standard. The API standard 650 aboveground petroleum storage tanks head polishing can adopt different technology according to different requirements, including rough polishing, medium polishing and fine polishing. Only the materials used for the third type of pressure vessels must be retested, and the materials used for the first and second class pressure vessels are not generally re inspected.
