Blind Flanges are characteristically produced without a bore. This is why a blind flange could be used across piping systems to blank off or seal off the ends of piping, Valves and pressure vessel openings. The ASME B16.5 Blind Flange is frequently produced from forged, cast, or plate materials.


From the standpoint of internal pressure and bolt loading, a 4 inch Slip On Blind Flange, particularly those manufactured in the larger sizes, tend to be the most highly stressed type of flanges.

What Is ASME B16.5 Blind Flange?


However, most of these stress or load are the bending type near the centre. And since there is no standard inside diameter, the ANSI B16.5 Threaded Blind Flange is well suited to be used for higher pressure temperature applications. Apart from several aspects covered by this standard such as pressure-temperature ratings, materials, Carbon Steel BLRF Flange Dimensions, tolerances, marking, testing, and methods of designating openings; the ASME B16.5 also takes into account requirements and recommendations regarding flanges gaskets, flanges bolting, and flanges joints. The Raised Face Blind Flange Pressure Ratinge is designated in the following classes i.e. 150, 300, 400, 600, 900, 1500, and 2500. Whereas the Stainless Steel Blind Flange is produced in sizes NPS 1/2 through NPS 24, with the requirements of these flanges mentioned in both metric and U.S units.
