API 650 carbon steel storage tanks inspecting requirements

The welded steel API 650 storage tank API 650 carbon steel storage tanks is designed, manufactured and installed on the surface according to the API standard system classification. API 650, API620 and API 12D belong to the API standards for professional construction.

Usually, the wind load in the API 650 carbon steel storage tanks construction area should be considered before the tank design and construction. The wind load in the API 650 carbon steel storage tanks construction area has an impact on the stability and economy of the API 650 carbon steel storage tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API 650 carbon steel storage tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.

The API 650 carbon steel 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.
