The marking, explained
Every flange is stamped on its rim, so it can be traced to its heat and its material certificate. Choose any part of the stamp to see what it means.
PN16Pressure
Nominal pressure PN 16. The pressure it can hold at a given temperature depends on the material.
HT 24A117 is a sample heat number. The stamp follows MSS SP-25.
