Determination of stiffness for large atmospheric-pressure storage tanks
Thread Content
Our company is currently manufacturing liquid caustic storage tanks with a diameter of 14 meters and a height of 18 meters. We would appreciate it if experts in this field could help us determine the appropriate material thickness as well as how to ensure the necessary stiffness of these tanks. Thank you
I vaguely remember that there is a standard for pressure vessels and the petrochemical industry that sets requirements for this.
JB4735-1997 for steel welded atmospheric pressure vessels – it specifies how to determine the material thickness and stiffness; generally, calculations are done manually, as there are no calculation software tools available
Go and look up this standard, “HG 21502.1-92 Series of Steel Vertical Cylindrical Fixed-roof Storage Tanks”, and refer to it for design purposes regarding volume as well as wall thickness. Then, verify according to JB/T4735 or the wind load on other large oil storage tanks to determine how many reinforcement rings are needed. Pay attention to your volume; check whether the volume specified in the standards falls within that range~
