Blind Flange
1/2" to 68" · 150 LBS to 2500 LBS / PN10 to PN400 · RF, FF, RTJ
A blind flange closes off the end of a run, a vessel nozzle or a spare connection left for a future tie-in, and takes the full rating of the joint it bolts to. Supplied from 1/2" to 68" in 150 LBS to 2500 LBS and PN10 to PN400, raised face, full face or ring type joint. The same material range as the rest of the flange programme: A105 and A350 LF2 in carbon, A182 in stainless, alloy, duplex and nickel. Drilled and tapped blinds for instrument or drain connections are machined to your drawing.
Rated the same as the joint it closes — no derating on a blanked line.
Instrument, vent and drain connections machined to your drawing.
Heavier test blinds for pressure testing supplied on request.
Size, rating, grade and heat number stamped on the outside diameter.
