miter elbow

[techwarrior08]

Please refer ASME 31.3 Para. 304 (Pressure design of Components) for help in design of miter bends.
Hope it helps.

Thanks for your attention
I go to Asme 31.3 para 304 and also read realated para such as 304.2.2&304.7.2&304.2.1
although I can't understand elbow 15 from 45 degree is correct or not?
Can you tell me how I realize it ?
Thank you so much
