EN 1092-1 flanges, either made from EN 10273 P250GH hot rolled bars or EN 10222-2 P250GH forgings, are classified into material group 3E0. The pressure-temperature ratings (p/T ratings) for P250GH indicate the maximum allowable pressure (M.A.S in bar unit) at maximum allowable temperature (Temp. in °C unit) for various PN designations of P250GH flanges. The p/T ratings are dependent on the actual flange thickness (vR in mm unit).
