Feature

• 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 safely be allowed to be higher than in other types of flanges.
• Blind flanges are made to fit standard pipes in all sizes.
