API standard 650 aluminum storage tanks scaffold-cable support

When encountering heavy rain or continuous heavy rainfall, the safe operation of API standard 650 aluminum storage tanks will be affected. For example: the API standard 650 aluminum storage 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 aluminum storage tanks in heavy rain.

Insulation Load
For API 620 tanks designed and constructed with an outer tank containing loose fill insulation in the annular space between the tanks, the insulation weight shall be divided equally to the inner and outer tank wall for seismic lateral loads unless a more rigorous analysis is performed to determine the distribution. The insulation within the annular space shall not be used to calculate resistance to overturning. Insulation on the API standard 650 aluminum storage tanks roof or suspended deck shall be applied to the tank supporting the load at the point or center of gravity of attachment and may be used to resist overturning.

The seismic effects on the tank wall of API 650 oil storage tank include the inertia moment generated by the weight of the API standard 650 aluminum storage tanks tank and the hydrodynamic pressure of the reservoir, which can be divided into short period pulse pressure and long period fluid slopping convective pressure.
