 Blind disk is the normal name of Flange cover, which is also called blind Flange or pipe plug.It is a flange without hole in the middle, used to seal the pipe mouth.The function is the same as that of the head and the cap, except that the blind plate seal is a removable sealing device, and the head seal is not ready to open again.There are many types of sealing surface, including plane, convex, concave and convex surface, tenon groove surface and ring connection surface.Materials: carbon steel, stainless steel, alloy steel, copper, aluminum, PVC and PPR.

Blind plate from the appearance, generally divided into plate plate blind plate, 8 word blind plate, insert plate, and pad ring (insert plate and pad ring each other blind).Blind plate plays the role of isolation, cutting off, and head, pipe cap, welding plug plays the same role.Due to its good sealing performance, it is generally used as a reliable means of isolation for systems requiring complete isolation.A plate-type flat blind plate is a solid circle with a handle used for normally isolated systems.The figure 8 blind plate is shaped like a figure 8, with the blind plate at one end and the throttle ring at the other end, but the diameter is the same as the pipe diameter, so it does not play the role of throttle.8 type blind plate, easy to use, need isolation, use blind plate end, need normal operation, use throttle ring end, also can be used to fill the blind plate installation gap in the pipeline.Another feature is the easy identification of the installation status.
