API standard 650 mixed material tanks seismic base shear
Welded steel API standard 650 mixed material tanks storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API standard 650 mixed material tanks all adopt on-site production and installation of storage tanks.
When encountering heavy rain or continuous heavy rainfall, the safe operation of API standard 650 mixed material tanks will be affected. For example: the API standard 650 mixed material tanks is submerged, the oil unloading valve and the flame arrester valve are broken by water and the oil tank leaks. The oil tank area must do emergency work to prevent rainstorm to ensure the safety of the oil tank. Here are some safety protection measures for API standard 650 mixed material tanks in heavy rain.
In this project, a cylindrical tank 62 ft 6 in. in diameter is designed for an internal pressure of 4 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 steel with appropriate grades for different plate thicknesses in accordance with Table 4-1 for a design metal temperature less than 65°F but not less than 25°F. No corrosion allowance is required for any portion of the tank. The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The roof is a single lap-welded spherical dome with an internal radius of 50 ft and a thickness of 1/4 in. The maximum design liquid level is 6 in. below the plane of the juncture of the tank API standard 650 mixed material tanks roof and sidewall.
