Re: [MW:25642] Damaged RF

You can refer ASME PCC1 or PCC2 according to your requirements . Gives you the acceptance criteria and machining allowances .

Hai,

See ASME B16.5 Cluase 6.4.6 for acceptance on Flange Facing Finish Imperfections.

Verify with the comparator for machining finish

Generally 3.2 to 6.4 micrometers AARH is acceptable.

Dear experts,

A  2" RF WN flange gasket (or raised surface) area got blasted by oversight and NCR was raised by our client. We have done milling -machining on the surface to restore the raised face and it looks OK and acceptable but the client is asking for machining report.

How is it done, I mean to confirm that the flange is acceptable?

Can we see a standard report of such machining.

Thankfully,

Vijay Joshi
