GOST 12820 PN25 FLANGE
The best practice is to use a standard gasket for these blinds. Blind flanges.
Just like standard pipe flanges, can be raised face (RF) or flat faced (FF).
Product Details
A blind flange is a solid flange as shown below. The purpose of these is to block off a section of
pipe or a nozzle on a vessel that is not used. (A nozzle is typically a pipe coming out of a vessel and
is usually flanged so it can be connected to valves or piping). Many times a nozzle will be blanked
off with a blind flange for pressure tests in a plant, or simply because the customer does not need
all the nozzles that were supplied on the tank.
