Regarding the verification of SW6 flange strength
Thread Content
I have a pressure vessel with an elliptical head, and the openings in the head are fitted with plate flat-welded flanges. I would like to know whether in this case it is possible to use SW6 to calculate the thickness of the flanges, or whether I should instead refer to HG20592. Thank you~
Is what the original poster means is that the pipe flanges on the end caps are made of plates, but should the thickness of these flanges be determined according to SW6 or in accordance with the flange thickness specifications outlined in HG20592?
Select standard flanges according to the operating conditions; no calculation is required...
Calculate using SW6. There’s no need to calculate when HG20592 is an option.
I understand what the original poster means: is it to use a plate-type butt-welded flange as the flange structure, and where exactly on the socket head should the openings be made?
