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.

Blind Flange Product Description:

Blind Flange Advantages

a) Superior surface finish
