The API standard 650 welded steel oil storage tanks stiffener ring and backing strip (if used) are primary components, and they shall comply with the requirements of API 620 storage steel tank Q.2.1. The stiffener rings may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange.
Except for aluminum or stainless steel tanks, all fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole (see Figure Q-1), and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to the detail that includes stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.

The main advantages of the external floating roof API standard 650 welded steel oil storage tanks are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API standard 650 welded steel oil storage tanks, the production of external floating roof API standard 650 welded steel oil storage tanks is simple and the steel consumption is less. However, the central drainage system of external floating roof API standard 650 welded steel oil storage tanks should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.
