Minimum wall thickness of spherical tanks larger than 400 cubic meters
Thread Content
I recently built a spherical tank. The design pressure is very low. According to the design pressure, the wall thickness is only a few millimeters. At the same time, the wall thickness of the spherical shell plate at the pillar is determined according to the stress at point a.
This topic is interesting. I hope anyone with experience in the design and processing of spherical tanks can express their opinions! :handshake
If you use 20R, you may need 30 thick
Is it necessary for such low-pressure equipment to be made into a spherical tank? Spherical tanks are very expensive to manufacture and should be considered economically to see if they are worth it.
The wall thickness of the spherical tank is related to the nature of the material contained. The corrosiveness of the material determines the corrosion margin and affects the wall thickness of the spherical tank.
The wall thickness depends on the specific design parameters. The manufacturer's tablet pressing is indeed related to the thickness, but it is also related to the designed segment size. Larger segments require larger thicknesses, otherwise it will be very difficult to control punching deformation!
From the perspective of production, transportation and installation, the 400m spherical tank should not be smaller than 16mm.
Depends on what it is used for, generally speaking it should be more than 8
There were about 16 of us, I don’t know exactly how big they were. It's probably as big as the original poster said.
I also really want to know the answer to this question, but I haven’t found any conclusive information.
