There is a problem related to conical heads that needs to be addressed in the design
Thread Content
External pressure conical head: the large end of the conical shell and the large end of the cylinder require reinforcement sections. For example, the cone 18 is thick, the reinforcement section 21 is thick, and the cylinder reinforcement section 21 is thick. Can I replace the reinforcement section with 18 thick cylinders and conical shells, along with 8 thick full-circle panels?
I don’t think so; I’ve never seen it done that way. Take a look at the opinions of other experts
No. You can try using a reinforcement ring design.
From the perspective of the actual manufacturing process, it is very difficult to ensure a tight fit for the entire circumferential strip of material; as a pressure vessel, this naturally results in the formation of two pressure chambers, rendering the strip of material ineffective!
Well, I think the same way. Do some design firms use additional plates to handle the thickened sections required for shaft-type lugs, which is different from this approach?
I think there is a difference between these two scenarios. In the case of equipment lugs, such as those found on tower vessels in a tubular shaft design, reinforcement of the plates surrounding the area where the lug is located is done to account for the lifting loads. This is done to prevent excessive local stress and stiffness at that location during lifting, and it’s different from the situation with pressure vessels subjected to external pressures.
No support lines are designed based on the larger or smaller end of the conical shell; instead, reinforcement rings are installed.
Calculate using the large and small ends of the conical shell as the support lines, and install reinforcement rings; check whether 18 layers of thickness are sufficient.
The method of attaching plates cannot be used. This is a case of external pressure-induced instability; axial lugs are mainly related to local stress issues, which is different.
