Blind flange, also known as blind flange. It is a connection form of flange. It's basically a flange without a hole in the middle. One of its functions is to block the end of the pipeline, and the other is to facilitate the removal of debris in the pipeline during maintenance. There are many types of sealing surface, including plane, convex surface, concave and convex surface, mortise and groove surface and ring connection surface. Materials are carbon steel, stainless steel, alloy steel, copper, aluminum and so on.
The Function and Classification of Flange Spectacle Blind:
From the appearance, blind plates are generally divided into plate-type flat blind plates, 8-shaped blind plates, slide plates, and gasket rings. Blind plates serve to isolate and cut off, and their function is the same as that of end caps, pipe caps, and welded plugs. Due to their good sealing performance, they are generally used as reliable isolation means for systems that need to be completely isolated. A plate-type flat blind plate is a solid circle with a handle, used in systems that are usually in an isolated state. An 8-shaped blind plate, shaped like an 8, has a blind plate at one end and a throttling ring at the other end, but the diameter of the throttling ring is the same as that of the pipe and does not have a throttling function. The 8-shaped blind plate is convenient to use. When isolation is needed, the blind plate end is used; when normal operation is required, the throttling ring end is used. It can also be used to fill the installation gap of blind plates on pipelines.
