Flanges

The high hub 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 high hub 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 high hub 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.
