API standard 650 cylindrical liquid-storage tank internal structures
API standard 650 cylindrical liquid-storage tank Drain hole: The drain hole is generally installed at the bottom of the oil tank, used to remove sludge when cleaning the oil tank, and usually used to drain the sewage in the tank. API standard 650 cylindrical liquid-storage tank Safety valve: The role of the safety valve is to play a safety role when the breathing valve fails during the operation of the oil tank. Its working pressure is slightly higher than the pressure of the breathing valve, which can prevent the tank from being damaged due to the high positive or negative pressure in the tank. The safety valve is usually installed in the middle of the API standard 650 cylindrical liquid-storage tank top.
Shell Stiffening Rings for Tanks That Contain Liquid: Internal or external shell stiffening rings may be required to maintain roundness when the API standard 650 cylindrical liquid-storage tank is subjected to wind, vacuum, or other specified loads. When stiffening rings are required, the stiffener-to-shell weld details shall be in accordance with Figure R-1 and R.3.5.2 through API Standard 620 R.3.5.5. Three-plate laps or butt-weld junctions in the tank bottom shall be not closer than 12 in. from each other and/or the butt-welds of the annular plate.
For areas with high groundwater levels, the operator should take anchoring and anti-floating measures for buried horizontal API standard 650 cylindrical liquid-storage tank oil tanks; API 650 oil tanks can be used for heavy fuel oil, heaters are separately designed, and buried tank material outlets are installed with bottom valves and connections. consider.
