Blind Flange JIS

Flange blind (blind flange), also known as blind flange, real name is blind. It is a form of connection of flanges. In fact, it is 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 easily remove debris in the pipeline during maintenance. In terms of plugging effect, it has the same effect as the head and cap. But the head is not disassembled, and the flange blind is bolted and easy to disassemble. Flange blind plate materials are carbon steel, alloy steel, stainless steel, plastic and so on.

The flange blind plate plays the role of isolation and cutting, which is the same as the role of the head and cap. Due to its good sealing performance, it is generally used as a reliable means of isolation for systems that require complete isolation. A blind is a solid circle with a handle that is used in systems that are normally isolated. The figure 8 blind plate, shaped like figure 8, is a blind plate at one end and a throttle ring at the other end, but the diameter is the same as the pipe diameter of the pipe, and does not play a throttling role. Figure 8 blind, easy to use, when isolation is required, use the blind end, when normal operation is required, use the throttle ring end, but also can be used to fill the installation gap of the blind plate on the pipeline. Another feature is the obvious marking and easy identification of the installation status
