Flanged joint pipe/valve FF/RF 1

[engdrve]

I am far in the field I am installing a pipe water line 3 kilometers long, ASTM A53 Gr B 6" Dia. 100 psi nominal presure. The piping arrived fabricated and painted with Welded neck RF flanges at de ends. And the gate valves arrived with FF flanges. What would be de consequense of joining the pipe with RF fanges to the valves with FF flanges. Thanks for the advise
