Does edge trimming affect strength when the cylinder and head have different thicknesses?
Thread Content
For example, consider a piece of equipment with a spherical head; the calculated value for that is 24, while the value for the cylinder is 42. In the actual manufacturing process, the edges of the cylinder must be trimmed, and that should affect its strength, right? Is it necessary to increase the head thickness to match that of the cylinder? ? ?
During the actual manufacturing process, it is not possible to trim the edges of the cylinder, as that would affect its strength. It can be handled with reference to Figures d), e), and f) in GB150.3-2011 D.2.2...
For those under 60mm, an elliptical head is a better choice; there’s no need to use a spherical one.
As requested by the client, I still find it a bit difficult to understand what is meant by the 2nd and 3rd floors. The diagram provided indicates requirements for edge trimming, but in practice, such trimming will affect the strength of the structure, as the thickness of the cylinder exceeds that of the end caps.
The cylinder cannot be trimmed, as that will affect its strength

Take a close look – where is the tangent line, and which part of the edge of the cylinder has been cut? d and e are actually cylinder shapes with hemmed edges; f represents a surfacing transition. All three methods of d, e, and f are acceptable – choose the one that suits your company’s machining capabilities and production capacity.
Please pay attention to where the tangent line is.
At 150, although after trimming the edge it is located in the cylinder section before welding, in actual calculations that trimmed area is considered part of the head; it’s just that later it is welded together
It’s pretty impressive; I really had no idea what it was for :（）
