ASME B16.34: Material not covered

[gazman2]

Hello,

I have to design a valve cl-2500 according to ASME B16.34, but the material is A694 F65. This material is not covered by this standard.

So, which pressure/temperature rating is to be followed?


Thank you in advance !!!

I would suggest that this question is not one to be answered by some anonymous clown (i.e. someone like me) on a free internet forum where the advice you get is worth every Euro you pay for it, but rather something which should be a matter of agreement between you, the designer, and the owner/user's engineer.

A letter to ASME and API might be a good thing too.

Hello,

B16.34 allows other materials than those directly listed provided they are listed in the boiler pressure vessel code with allowable stress versus temp. values. If so, then you establish the pressure - temp. rating per the method defined in B16.34. If the material is not in B16.34 or the boiler and pressure vessel code, it cannot be a 16.34 valve.
