Ansi B16.5 Jis B2220 Din2633 Stainless Steel Blind Flange Pn16

Flange blind plate, the real name is blind plate. 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 facilitate the removal of debris in the pipeline during maintenance. As far as the blocking effect is concerned, it has the same effect as the head and the cap. However, there is no way to disassemble the head, and the flange blind plate is fixed with bolts, which is very convenient to disassemble. Flange blind plates are made of carbon steel, alloy steel, stainless steel, plastic and so on. Due to its good sealing performance, it is generally used as a reliable means of isolation for systems that require complete isolation. A blanking plate is a solid circle with a handle for systems that are normally isolated.

The figure 8 blind plate is shaped like a figure 8, with a blind plate at one end and a throttling ring at the other end, but the diameter is the same as the diameter of the pipe and does not play a role in throttling. Figure 8 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 identification, easy to identify the installation status.
