hi all
Should Pump Flanged Nozzle rating should MATCH( strictly) with the rating of Flange of connecting pipe to that nozzle ?
I mean suppose if the suction nozzle of Boiler Feed Pump is ( ASME CLASS 300 RF)
then the connecting flange ( Piping scope) should be of same rating (ASME CLASS 300 RF) NO MORE NO LESS
