Normalizing Flanges
Normalizing Flanges
(OP)
Hey all,
Many B16.5 steel flanges I've come across are made from A105N steel. I thought I had read a standard that required all Class 600 & higher rated flanges to be normalized. Looking through B16.5 & B31.4 today I could not find this requirement anywhere. Does anyone know if this is a specific material requirement under any pressure piping standard (B31.3, B31.4, etc.) or regulation (49 CFR 195, 192, etc.)?
Thanks for your help in advance.

Have a look at the linked document for the need for A105N:
