Pressure-Temperature Ratings
General
Temperature ratings using psi units for pressure in degress Fahrenheit
MIX Working gage pressure in bar units at degrees Celsius
Flanged joints
flanges, gasket, bolting
Bolt tightening->ASME PCC-1
Mixed Flanged joints
if not the same pressure-temperature ratings, the rating of the joint at any temperature is the lower of the 2 flange ratings at that temperature
Rating temperature
