Wall thickness issues of large storage tank containers
Thread Content
For an oil storage tank with a diameter of 4000 mm, a volume of 120 cubic meters, and a cylinder length of 8200 mm, is a wall thickness of 14 mm sufficient? Do I need to strengthen the ring?
The conditions you mentioned are incomplete; the design pressure and design temperature are not specified
2# abc10000d: at atmospheric pressure, temperature of 320 degrees
It’s sufficient; no additional addition is needed. But considering heat insulation, adding some reinforcing rings can serve as a support for insulation
It should be calculated according to specific design standards!
Our company’s oil storage tanks do not have reinforcing rings; they have a capacity of 10,000 cubic meters, the steel plate thickness is around 6 millimeters, and the two bottom plates are used together.
SW6, calculate to see if it meets the requirements
It is necessary to calculate whether reinforcement is required; the analytical design method can be employed； Calculate using finite elements
A specific calculation is needed to determine this; the pad plate of the saddle can be made wider and used as a reinforcement ring, which will allow for proper calculation of the saddle as well as sufficient reinforcement for the cylinder.
Let’s stick to the design technical requirements, after all, there are many influencing factors. Such as capacity, liquid density, operating pressure, structural materials, foundation design, site conditions, and permitted height.
