The jar swelled up
Thread Content
Dear marine friends, I have a question: For a cylindrical storage tank with a large diameter, when it is placed vertically on a horizontal surface, why does the bottom of the tank bulge? Is there any theoretical explanation for this?
The bottom of the storage tank is designed with a taper; from the perspective of fluid flow, this facilitates drainage and complete emptying； From the perspective of physical stability mechanics, this method is more stable. The effect on the wind bending moment and seismic bending moment of the entire tank is more significant. For reference only!
In a situation like this, it must be a tank that does not have foundation bolts installed. Because the storage tank has a certain internal pressure, and the lifting force generated by this pressure is greater than the weight of the tank walls and roof, this situation occurs. If the lifting force is greater than the weight, it is necessary to install foundation bolts.
I didn’t understand; is the poster saying that the bottom of the container is deformed and bulged? I also didn’t understand the answers from the two people above; how can one tell from the poster’s description whether it’s a tapered layout or a floating roof?
On the fourth floor, Wen Bing understood it correctly: the bottom of the jar bulges out, which means it appears indented from the outside! How should I explain this? I seem to have heard of it when I was reading before; I just don’t know which book to look it up in Please give some advice!
I can’t understand it; please post a photo, OP.
Is A Shi sunken? What causes the bottom plate to warp?
This kind of deformation occurs in the welding at the bottom of large tanks; it is required that the depth of local unevenness deformation should not exceed 2% of the deformation length, and should also not be more than 50 mm.
Buoyancy causes external pressure instability of the head; therefore, an external pressure check is required for the head
Thank you. It seems to be the rounding effect!
