Joint Blind Flange :

ANSI B16.5 Ring Type Joint Blind Flange :

Some important features of blind flanges are as follows:
Carbon Steel Blind flanges are sometimes supplied with NPT fittings which allow pressure
test connections to be fitted;
Blind flanges are used to blank off the ends of pipe;
Blind flanges 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 safely be allowed to be higher than in other types of flanges;
Blind flanges are made to fit standard pipes in all sizes.
