Embedded takeover flange width?
Thread Content
For high-pressure vessels, how much should the flanging of the nozzles generally be? And what should the transition radius be? Are there any standards or manuals available for reference?
No, quite few; it is determined based on engineering experience, especially regarding the bend radius R. The designer is required to find a balance; by determining the thickness of the cylinder and the thickness of the forged tube, the minimum bending radius can be calculated – this is what I have concluded.

Could you send me your table, if that’s possible?

In terms of strength, larger radii are certainly better, but cost also needs to be taken into account; the larger the radius, the larger the outer diameter of the reinforcing element. There is no specific standard for the exact size of the round corner R; as long as it is calculated correctly, that’s sufficient.
In our designs, the flange width is generally larger than the stress attenuation dimension, and R is greater than wall thickness/4.
How can I find the stress decay range?
