Usage:
The function of the carbon steel blind flange is to isolate and cut off. It's the same thing as the cap. Due to its good sealing performance, it is generally used as a reliable means of isolation for systems requiring complete isolation.
Notes:
1. On the premise of meeting the technological requirements, as little as possible carbon steel blind flange.
2. The blank flange must be marked normal open or close.
3. The position of the carbon steel blind flange is located at the cutting valve, upstream or downstream, which should be determined according to the cutting effect, safety and process requirements.
