A105 and A105N Flanges
A105 and A105N Flanges
(OP)
Do flanges class 600# and above require to be stamped A105N? Or would it be ok for just the MTR to state the flange is A105N?

Also, the terminology used answered your question.
"Should" means recommended but not mandatory. As opposed to "shall" which means it's compulsory.

the flange will need to be stamped SA105N and the MTR's will have this info also. Same with couplings. The A.I. will not accept.

if thats what the ASTM A105/ASME SA 105 standard requires, then you and the AI are correct
