Duplex Steel S31803 Blind Flanges

Duplex Steel S31803 Blind Flanges plays the role of isolation and cutting, and the role of the head, tube cap, welding plug is the same. Because of its good sealing performance, for the need to isolate the system, generally as a reliable isolation means. A plate plate blind plate is a solid circle with a handle used in normally isolated systems. The figure 8 blind plate is shaped like figure 8. One end is the blind plate and the other end is the throttle ring, but the diameter is the same as the pipe diameter, so it does not play the throttling role. 8-figure blind plate, easy to use, need isolation, use the blind plate end, need normal operation, 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 that it is clearly marked and easy to identify the installation status.
