How to calculate the pressure-bearing capacity of a storage tank based on the thickness of the steel plate? If the diameter is 8 meters, the height is 5.5 meters, the thickness of the top plate is 6 mm, and the thickness of the bottom and side plates is 8 mm, how can we calculate the maximum pressure capacity of this tank? What is the maximum positive pressure it can withstand, and what is the maximum negative pressure it can withstand? Thank you
What material? I can help you do the calculations, but I can’t send you the calculation sheet. We calculated it using our own Excel spreadsheet
You can delete the formula and send it as an image instead
I’m not sure what the original poster’s intention is; when calculating large tanks, it’s not just pressure that needs to be taken into account, but also wind load. For negative pressure, attention must also be paid to the cylinder reinforcement rings as well as the reinforcement structures for the tank wall and tank roof.

It doesn’t need to be very precise. I am considering that our company is planning to carry out a nitrogen sealing renovation for the methanol storage tanks this year. Because the pressure in our main nitrogen pipeline is 20 kilograms, it is reduced in two stages to 0.05 MPa before entering the storage tank. I’m wondering how much positive pressure the storage tank can withstand if the pressure relief valve fails and at the same time the flow rate from the breathing valve is insufficient. Additionally, there is a possibility that the nitrogen main pipe in our facility could experience a loss of nitrogen supply; therefore, I’m considering how much negative pressure it can tolerate I’m a beginner; I’m just learning*, without a clear goal.
There is a formula for this; it’s necessary to know the allowable stress of the material. There are various types of carbon steel, as well as the design temperature. One then needs to look up the formula in the pressure vessel specifications and carry out the calculations oneself. As a reminder, if there is static liquid pressure involved, don’t forget to take that into account. The simplest way is to check the nameplate or consult the equipment diagram – it’s not that complicated.
