Strengthening calculation for openings in hemispherical heads
Thread Content
There is an opening in the hemispherical head; when performing calculations for strengthening due to this opening, which value, h1 or h2 in the diagram, represents the effective external strengthening height? I would appreciate it if someone could give me some guidance. Thank you!
Thank you. I discussed it with my colleagues and looked up some information; it should be h1
I think, strictly speaking, it shouldn’t be H1; it should be something slightly smaller than H1
What was meant upstairs is that it should be the distance from the intersection of the inner diameter of the pipe fitting and the end cap to the end of the pipe fitting
Personally, I think it can be calculated using H2 as a conservative estimate; if that value isn’t sufficient, then the calculation can be done using the intersection point of the take over inner diameter and the head
H2 is hypothetical; it does not exist in reality.
This is indeed the case; it’s practically impossible to measure
H2 is indeed conservative; it just increases costs.
I just want to see if I can find some theoretical basis somewhere.
