Flange Finsh
(OP)
Hi Guys,
Just being bussy specifying the flange finish for and ANSI B16.5 raised face flange for a ejector mixer. We are using graphite envelope gaskets with stainless steel insert. I can specify serrated spiral or concentric grooves in the raised face surface. Which type of grooves do I speciffy when ??
Thanks for any reply

Similarly, at least in my mind, Most lip seal manufacturers specify a plunge ground sealing surface (creating pure circumferential grooves, not helixes) in addition to a surface finish when leaks must be minimized.
