The guidelines covered by the ANSI B16.5 standard include pressure-temperature ratings, materials used to make the flanges, high hub blind flange dimensions, tolerances, testing, marking, and methods of designating openings for the different type of flange. Furthermore, the ANSI B16.5 standard also includes other details pertaining to the ASME B16.5 High Hub Blinds Flange such as requirements and recommendations in terms of the bolting used, flange gaskets, and flange joints. Carbon steel High Hub Blind Flanges are used to seal the ends of the pipe structures in a system. These flanges are constructed with a type of circular plate without any centre hold but the circular plate is will have all the right bolt holes. Depending on its use, a high hub blind flange could be produced in a variety of sizes and materials. Most commonly the materials used in their manufacture are carbon steel, alloy steel as well as various stainless steel grades. A High Hub Blind Flange can be used to provide a constructive closer at the ends of pipes, equipment, valves or nozzles.

Once it has been sealed, these Stainless steel High Hub Blind Flanges permits the worker to easily access the line or piping system. On several occasions, a high hub blind flange can be specially built or machined in order to match the nominal size of the pipe to which this particular reduction has been made. This reduction done on these flanges could be either a reduction in threads or it could be a reduction in welds. Frequently these high hub blind flanges are supplied with NPT fittings. These fittings in turn sanction the installation of pressure test connections. Considering factors such as internal pressure and bolt loading, ANSI B16.5 High Hub Blind Flange is reckoned to be the most stressed amongst all types of flanges, particularly in the larger sizes.
