Strength calculation of pressure vessels
Thread Content
According to GB150.3, the applicable scope for cylinder calculations is Pc
There are also analysis and design standards, 4732. But it generally shouldn’t exceed that, right?
In that case, the pressure is in the range of dozens or hundreds or even higher, and the wall thickness is very large; therefore, the standard formulas are not very applicable, and a design based on high-pressure or ultra-high-pressure conditions is required
When this range is exceeded, that is, when D0/Di > 1.5, it refers to thick-walled containers; in such cases, it is necessary to take into account the three types of stresses: radial stress, hoop stress, and axial stress. Except for the axial stress, which is uniformly distributed, the other two types of stress are not uniformly distributed. The Lamé formula should be used to calculate these stresses, and the relevant calculation formulas can be found in GB150.3-2011, page P107.
