Blind Flange
The blind flange is a flange without a hole in the middle, used to seal the end of a pipe. Its function is the same as that of a head and pipe cap, except that the blind flange seal is a removable sealing device, while the head seal is not intended to be reopened. There are various types of sealing surfaces, including flat, convex, concave-convex, tongue-and-groove, and ring connection surfaces. It is mainly used to completely isolate the production medium, preventing issues caused by improperly closed shut-off valves, which could affect production or even cause accidents. It should be installed at points requiring isolation, such as at the equipment connection, before and after shut-off valves, or between two flanges. The spectacle blind is commonly recommended.
