Surface Finish Of Girth flange

[Ronak_Patel]

what should be the surface finish of kammprofile gasket with male and female flange face ?

according to ASME B16.5 Male and female face type can have max 125 micro inch finish but according to ASME PCC -1 kammprofile (grooved metal) can have max 63 micro inch only .

Ronak_Patel, kammprofile gaskets having a soft facing do not need an especially fine surface finish to seal. Flexitallic recommends them as direct replacement for jacketed gaskets, for which surface finish is usually 125 - 250. Unfaced, grooved metal gaskets would require a finer finish. Both finishes are as per Apx C.

The problem with sloppy work is that the supply FAR EXCEEDS the demand
