Quick Overview

Blind flange is a kind of round plate with no center hole but with all the proper bolt holes. It is used to blank off the ends of piping, valves and pressure vessel opening. From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed of all flange types; however, since the maximum stresses in a blind flange are bending stresses at the center, they can safely be permitted to be higher than in other types of flanges. This blind flange is available in various sizes and materials. This flange helps in easy access to a line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sized pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction. They may often be supplied with NPT fittings to allow pressure test connections to be fitted These Flanges are available in the following range.
