Blind Flanges

Our organization offers a wide range of Blind Flanges and Stainless Steel Blind Flange, which is widely used to close ends of piping systems. These Blind Flanges are round plate with no center hold but with all the proper bolt holes. We offer our range of Blind Flanges in various sizes and material, which is used to provide positive closer on the ends of pipes, valves, or equipment nozzles. The Blind flanges also help in easy access to a line once it has been sealed. These Blind Flanges are available in custom made finishes or in standard sized pipe to which reduction is being made. Further, this reduction can be a threaded reduction or welded reduction.

FEATURES

Blind flanges are sometimes supplied with NPT fittings which allow pressure test
Connections to be fitted
These are used to blank off the ends of pipe
Used to blank off the ends of valves and pressure vessel opening
Considering factors like internal pressure and bolt loading, blind flanges, especially in the larger sizes, are the most highly stressed of all types of flanges
Since the maximum stresses in a blind flange are bending stresses at the center, these can safely be allowed to be higher than in other types of flanges
Blind flanges are made to fit standard pipes in all sizes
