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 th…
