Blind Flanges
Blind Flanges are used to blank off the ends of piping, valves and
pressure vessel openings. Blind Flanges can handle high stress from
internal pressure and bolt loading since the maximum stresses in
the blind flange are bending stresses at the center.

Blind - Blind Flanges (BLRF)
A popular category of pipe flange is the blind flange. A blind
flange is used to close ends of piping systems. It is a kind of
round plate with no center hold but with all the proper bolt holes.
This blind flange is available in various sizes and materials and
is used to provide positive closer on the ends of pipes, valves or
equipment nozzles. 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. |

Features of Blind Flanges:
Some important features of blind flanges are as follows:
- Blind flanges are sometimes supplied with NPT fittings which allow
pressure test connections to be fitted.
- They are used to blank off the ends of pipe.
- They are also 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, they can ely be allowed to be higher than in other
types of flanges.
- Blind flanges are made to fit standard pipes in all sizes.
