Quick opening blind plate generally divided into four kinds: forging, casting and forging, casting, plate cutting system. The forging products of the highest price, the lowest in the plate, casting and forging. Casting is the most time of a process. The quality is good in forging and casting, to be slightly worse. Blind plate isolation, cut off, and the welding head, pipe cap, plug the role is the same. Because of its good sealing performance, for the need to completely isolate the system, generally as a reliable means of isolation. A 8 word blind plate is a solid circle with a handle, used in a system of isolation. The 8 word blind plate, shaped like 8 words, one end is a blind plate, the other end of the throttle ring, but the diameter of the pipe with the same diameter, does not play the role of throttling. 8 word blind plate, easy to use, need to be isolated, the use of blind plate side, the need for normal operation, the use of the throttle ring end, but also can be used to fill the pipe on the installation of blind plate gap. Another feature is the obvious identification, easy to recognize the installation status. Blind flange used in galvanized oil medium system, the system should be used for other medium hot galvanized, zinc dipping layer minimum weight 610g/m2, 


hot galvanizing quality inspection according to CB*/Z343. The blind plate shall be provided with a separate (cut) part, such as a device nozzle, cut off valve, or between the two flanges.
