Mating surfaces of flanges
Mating surfaces of flanges
(OP)
Can someone advice me where I can find the norm (what norm?) for finish, flatness and waviness specifications, for mating surfaces of flanges.
Many thanks

MSS SP-6 for B16.1 for cast iron flanges

For Surface finish also refer B46.
Also you may Refer to TEMA this gives allowable defects in Raised face of Gasket face. Scratch marks, scoring etc are given here. you may use these as Norms.

Great stuff, does it (ASME PCC1) give acceptable defect size in RTJ type flanges?

It doesn't have any flatness requirements specific to ring joint flanges. Note B16.5 has a surface finish requirement for ring joint flange grooves.
