The formal name of
Blind Flange is flange cover, and some are also called blind flange or pipe plug. It is a flange without a hole in the middle, which is used to block the pipe mouth. It has the same function as the head and the pipe cap, except that the blind plate seal is a detachable sealing device, and the head seal is not ready to be opened again. There are many types of sealing surface, including plane, convex, concave convex, mortise and groove surface and ring connection surface. The blind plate is mainly used to completely isolate the production medium, prevent the production from being affected or even cause accidents due to the loose closing of the shut-off valve. The blind plate shall be set at the part requiring isolation, such as the nozzle of equipment, the front and back of shut-off valve or between two flanges, and it is often recommended to use the spectacle blind plate; the plug-in plate (circular blind plate) can also be used for the part requiring one-time use such as pressing and purging.
