Also called blind flange, blind plate. It is a flange without a hole in the middle, which is used to seal the pipe plug. The function is the same as the welding head and the threaded pipe cap, except that the blind flange and the threaded pipe cap can be removed at any time, while the welded head cannot. There are many types of sealing surfaces, including full-plane, raised surface, concave-convex surface, tongue and groove surface, and ring connection surface. The main production area is around Mengcun.
