ASME SA815 F304 304L Pipe Fitting Flat Face Blind Flange ASTM A815
ASTM A815 / ASME SA815 304/304L Pipe Fitting Blind Flange
Blind Flange:
Blind flange is a solid disk used to block off a pipeline or to create a stop. Similar to a regular flange, a blind flange has mounting holes around the perimeter and the gasket sealing rings are machined into the mating surface. The difference is that a blind flange has no opening for fluids to pass through.
