Hi I am looking for some pressure vs temperature ratings for AWWA flanges. Specifically I am using a 28" Class E flange and would like to know its pressure rating at 200^F. It seems there should be some sort of chart for this similar to the one in the piping guide for ANSI flanges.

pressure/temperature ratings for AWWA flanges

This website will give you the pressure at ambient. I don't know how AWWA handles reduction in ratings versus temperature. At 200°F there shouldn't be no reduction in rating based on the material of construction.
