    XL83NL yes, I see the drawing, I'm trying to be technical with a 12" dial caliper. I start measuring from one end of the 90, but how exactly do I find the center, being that the area where the exact center is, is round.

    I have a question. What tools do you use to find the center to end dimension on a 1/2" threaded 90 degree mallable iron fitting, and the correct way to obtain the accurate dimension? Can it be done with a dial caliper? Thanks for the advise in advance.

    Grinding on stainless steel pipe

    The reason for removing the scratches is just cosmetic purpose. It doesn't affect the wall to fall below the minimum tolerance. A flap disk is good, just wondering is someone knew osf a particular one that can be used on stainless steel without contaminating it.

    A105 and A105N Flanges

    Ripz and all, thanks for your help on this. Answer to my question is the flanges are good due to the fact that A105N is not mandatory to be stamped on the flange markings, just aslong as the MTR states "A105N" on class 600# and above flanges.

    Para S2.4 states " In addition to the marking required by Section 13, this specification should be followed by the letter: A for Annealed, N for Normalized, NT for Normalized and Tempered, or QT for Quenched and Tempered as appropriate". With that being stated, would the Class 600# flanges...

    A105 and A105N Flanges

    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?
