A662 grade C plates API Std 650 aboveground steel oil storage tanks

There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API Std 650 aboveground steel oil storage tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API Std 650 aboveground steel oil storage tanks edge sealing system to reduce edge evaporation. The support legs of API 650 crude oil tank floating roof are usually movable and retractable and suspended in liquid.

API Std 650 aboveground steel oil storage tanks Manhole: The manhole is used for the operator to enter and exit the oil tank for inspection, cleaning and repair. For the convenience of personnel access, the installation position of the manhole is generally on the center line of the oil tank bottom, and the vertical oil tank is installed at the lowest layer of the tank wall. API Std 650 aboveground steel oil storage tanks Light-transmitting hole: Light-transmitting hole is also called day-lighting hole. It is used for lighting and ventilation when inspecting, repairing and scrubbing the oil tank. It is generally installed on the top of the oil tank above the inlet and outlet pipes.

The API Std 650 aboveground 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.
