ANSI B16.47

[Tankman650]

Does ANSI B16.47 have a pressure/temperature chart like B16.5???

I have a B16.47 150# flange at 300 degrees and need to document the allowable pressure. I don't have the code but will get one if there are charts for pressure/temp.

Thanks.

Tankman650-

Yes, B16.47 (I have a 1990 ed.) has pressure-temperature ratings very similar to B16.5. A Class-150 material group 1.1, 1.2, or 1.3 flange would have a pressure rating of 230 psig at 300°F.

Thanks jte,

The 230 psi is the same as B16.5
