Vertical pressure vessel flat bottom
Thread Content
I would like to ask the experts: For a vertical storage tank with a flat bottom, and under a pressure of 0.1 MPa inside, how should the thickness of the flat bottom be calculated? Is it appropriate to calculate directly using the flat cover method? (Leg type)
It is possible to calculate directly using the flat cover method.
It can be calculated as a flat cover; select appropriate parameters based on the welded structure, and also pay attention to whether to consider the hydrostatic pressure of the liquid column.
Reinforcements are needed to reduce the wall thickness.
This pressure still requires a flat surface; it bulges as soon as pressure is applied: lol
It is advisable to add cross-shaped reinforcing ribs at the bottom of the device; this not only improves the load-bearing capacity but also reduces the impact caused by uneven foundations
The flat cover will bulge at 0.1; is it feasible to use the previously calculated thickness?
A regular bottom structure definitely won’t work; significant reinforcement is required, which is not cost-effective and not worth the effort
From the site, open-air tanks usually have foot bolts, but there are also those without them; for example, tanks with a low center have a bottom plate that is in the shape of an inverted cone, giving it a certain degree of mobility.
