JIS blind flange is a flange without a hole in the middle, which is used to block the pipe opening. The function is the same as that of the head and the cap, except that the blind plate seal is a detachable sealing device, and the seal of the head is not ready to be opened again.
There are many types of sealing surfaces, including flat surfaces, convex surfaces, concave-convex surfaces, tongue-and-groove surfaces and ring connection surfaces. Materials include carbon steel, stainless steel, alloy steel, copper, aluminum, PVC and PPR, etc.
From the appearance point of view, the blind plate is generally divided into plate-type flat blind plate, 8-shaped blind plate, insert plate, and backing ring (the insert plate and the backing ring are mutually blind).
The blind plate plays the role of isolation and cutting, which is the same as that of the head, pipe cap and welding plug. Due to its good sealing performance, it is generally used as a reliable means of isolation for systems that require complete isolation.
A plate blind is a solid circle with a handle and is used in systems that are normally isolated. The 8-shaped blind plate is shaped like an 8, with a blind plate at one end and a throttling ring at the other end, but the diameter is the same as that of the pipe, so it does not play a throttling role. The 8-shaped blind plate is easy to use. When isolation is required, the blind plate end is used. When normal operation is required, the throttle ring end is used. It can also be used to fill the installation gap of the blind plate on the pipeline. Another feature is the obvious marking, easy to identify the installation status.
