[MW:17247] Ra on Valve bodies- Required 125 - 250 AARH as per ASME B16.5.

Dear experts

Required RA  125 - 250 AARH as per ASME B16.5 on Plug Valve bodies (8inch size) But actually measures one end flange less than  80Ra  and other side flange  is more than 300Ra.

If it is more Ra how it is effecting in a valve site assembly.

Regards
