Effective reinforcement range of perforated reinforcement

This result suggests the use of local stress analysis. Refer to JB4732
From a safety perspective, this effective reinforcement width should be less than 600!
Is 600 too conservative? The reinforcement width on the end cap is not determined based on horizontal or vertical directions either. For axial openings, with the same fittings, the opening sizes vary depending on their position; in the drawings, there are two sizes – which one is reasonable?
Does your takeover fall within the range where equal area is not a strict requirement? Analytical methods can’t be used either; FEA is still the better option.

This structure seems a bit unconventional; could we change it to an eccentric cone shell?
Hello, may I ask which rule of the equal-area reinforcement method is violated by such an opening?
Any changes to the structure require user approval; the design done by the manufacturing unit is not on par with that of a design institute
The opening diameter, I estimate, is more than D/2
