How to calculate the overall reinforcement for openings in pressure vessel shells
Equivalent-area reinforcement is generally used——————————————————————————–
The effective reinforcement area must be greater than the required reinforcement area

It’s treated the same as regular reinforcement; there’s nothing special about it. Perhaps there is local thickening, but generally it goes beyond the scope of reinforcement
The cylinder is thickened, resulting in an effective reinforcement area that is greater than the required reinforcement area
The overall reinforcement works the same as regular reinforcement: it is sufficient that the reinforcement area is larger than the weakening area. But it’s better not to use overall reinforcement, as it’s too wasteful of material, especially for large installations. You can try using thicker connectors or whole forged parts first; as a last resort, increase the thickness of the main wall.
