What should be the maximum liquid level in a vertical atmospheric storage tank?
Thread Content
For a tank of 1000 M3 with a height of 10.5 M, should the maximum liquid level be set at 80% or 90%?
First, it is necessary to check whether there is a floating disk; if so, the maximum liquid level needs to be reduced by the height of the floating disk. Then, the time required to close the filling system must be calculated, and the increase in the liquid level of the tank during that time should be subtracted from this value – this will give an approximate value for the maximum liquid level
Is it not clearly specified that *the usual height should be within 80%?

Even if the manufacturing process improves, the maximum liquid level still needs to be determined – specifically, the wave height of the liquid surface in the tank under horizontal seismic forces. Under the new version of 50341, the allowable maximum liquid level can be reduced. In SH 3007-2007 P20, the value in the top row is generally set at 0.9, but it must not exceed 0.95
Normally: For tank top walls, the tube wall height is –800 mm; for floating roofs and roofed tanks, the tube wall height is –1000 mm. This value is determined accordingly
