Pressure numbers (PN) compare to ASME flange rating

[farzam]

Hi All,

Does someone know any reference regarding Pressure numbers (PN)for EN flange(En 1092) compare to ASME flange class designations?e.g what is equivalent rating in ASME flange compare to PN63?

Thanks in advance

Dear Fawkes,

In En1092, e.g for CS material(P245GH)PN is specified based on Temp-Pressure. Actually I have nozzle based on DIN(PN63 rating)but the nozzle load specification is based on ASME flange rating(150#,300#,...)so i need to find an equivalent for PN63 or PN100

Thanks

Hi Farzam, hi all,

I think you should better refer to EN 1759 which is specifically adressing "Flanges and their joints - Circular flanges for pipes, valves, fittings and accessories, Class designated".

EN 1092 is only for PN designated flanges, so it is not is the same scope.

With both standards in hands you could compare the pressure/temperature ratings!
