Blind Flange are more commonly used in industrial pipelines, and flange covers are also called blind flanges, blind plates, and flange blind plates. It is a flange without a hole in the middle. Generally, the pipe is not extended and is used to seal the pipe. The function of the blind flange is the same as that of the welded head and the threaded cap, except that the blind flange and the threaded cap can be removed at any time, while the welded head cannot. Therefore, the blind flange is more flexible in construction. If the pipeline needs to be extended, the blind flange can be removed and connected to other flanges. Flange cover sealing surface type: raised surface (RF), flat surface (FF), concave-convex surface (MFM), tenon and groove surface (TG), ring joint surface (RJ), etc. Generally, the RF surface flange cover is commonly used.
