How to use a large-angle cone as a bottom head in a pressure vessel at atmospheric pressure
Thread Content
The thickness calculated for large-angle cones based on the flat cover method is too large. However, in atmospheric pressure vessels, large-angle cones are often used as bottom heads due to process requirements. For vessels with smaller diameters, the wall thickness can be determined directly based on experience; but what about those with larger diameters? Can radial plate stiffeners be used to calculate the thickness in such cases? How to calculate
Calculated based on the reinforced flat cover (GB/T150.3, §5.9.5). If the calculation results are too absurd and unacceptable, then the finite element method must be used for modeling and verification.
