Stainless Steel Blind Flange does not breed bacteria. Neither does it rust nor does it erode. Threaded Blind Flange has a tapered pipe thread that helps it to fit into a similar counterpart thus creating a tight seal. They are used in piping systems where welding can be hazardous. Raised Face Blind Flangeis used to concentrate the surface pressure applied when mating with the flanges. It reduces the surface area of the flange. It has a machine serrated finish. A raised face flange creates a tighter seal when compared to a flat face flange. 

High Hub Blind Flange has a raised face without a hole in the center. It is used to provide closure at the end of the pipe. Flat Face Blind Flange has full contact with the surface and is bolted onto the pipe to close it. It is a type of flange that is supplied without a hub. A105 Blind Flange can handle high stress that is caused by the pressure exerted internally. It helps us to easily repair a system without removing an entire pipe. 316 SS Blind Flange resists crevice corrosion and pitting. It has good welding and forming qualities.

Features of blind flanges

Looking for Blind Flange manufacturers in India for custom sizes? One of the oldest producer of EN 1092-1 Type 02 Pn16 Blind Flange, AWWA C207 Aluminum Blind Flange in India

• 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.
