Blind Flanges RF

Our organization is engaged in manufacturing of a wide range of Blind Flanges that 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. These flanges are available in various sizes and material and are used to provide positive closer on the ends of pipes, valves or equipment nozzles. Our range helps in easy access to a line once it has been sealed. Further, these are machined to accept a nominal sized pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction.Materials used:

• Stainless Steel
• Nickel Alloy
• Titanium
• Carbon Steel
• Cast Iron
• Brass
• Bronze
• Steel
• Aluminum
• Polypropylene
• Silicone
• PVC

Features

• 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.
