AWWA flanges temperature
AWWA flanges temperature
(OP)
Hello,
I'm looking at AWWA C207 flanges and I want to know the highest temperature appropriate for each class of flange and its given pressure rating.
Section 1.3.2.5 states "Pressure ratings are for conditions and temperatures customary in water utility service."
What are the highest temperatures encountered in water utility service? If it's just ambient, what's ambient assumed to be?
So for instance if I have a Class E flange, which the AWWA spec rates to 275psi, what's the temperature of the water that can be in the line if the water is at 275psi? Can the corresponding saturated steam temperature of 275psi be used?
Any help appreciated.

"In waterworks practice, it is not necessary, within the scope of this standard, to deal with temperatures greater than the atmospheric range, and it is possible to restrict consideration to joints with softer gaskets and to flanges that are flat faced. The designs were prepared in conformity with these limitations."
[The reference to "saturated steam" is confusing.]
