I would like to ask experts about the design of the dome top for storage tanks
Thread Content
When comparing GB 50341-2014 with the book \"Comprehensive Guide to Chemical Equipment Design: Spherical Vessels and Large Storage Tanks\", the latter includes calculations for the stability of smooth spherical shells; GB 50341-2014, on the other hand, does not provide such calculations. As a result, it is difficult to determine whether ribs should be added to the spherical shell top according to GB 50341-2014. How can I decide whether ribs are needed for this type of spherical shell top? Moreover, for the book \"Comprehensive Book on Chemical Equipment Design: Spherical Vessels and Large Storage Tanks\", can I use the design external pressure at the vessel wall instead of that at the top of the spherical shell?
GB50341-2014 sets requirements for the thickness of the dome roof; if the thickness is insufficient, ribs must be added.
50341 Chapter 7: Weren’t we just talking about the tank top? 7.5 is for the calculation of a smooth arch roof!
It equals 7.5.2; does an additional value need to be added when the thickness exceeds 12 mm?
In other words, according to the thickness specified in 7.5.2, if it exceeds 12 mm, an addition is required?
We generally use 6mm thickness for ease of processing and manufacturing. The standard should not exceed 12
The standard should not exceed 12; for the purpose of saving materials, ribbing can also be used if a thickness of 10 is considered!
