The pressure temperature rating of Flanges as per UG-44 is in accordance with the appropriate standard e.g. B16.5, what shall be the pressure-temperature rating for MAWP calculation purpose for SA 266 grade flanges which P-T rating is not mentioned in B16.5?

As the material is unlisted, B16.5 rating cannot be applied. It must be rated by other means, i.e. Appenidx 2.
