Blind character suggests that it is shaped like eight words, it is the blind end of the convex surface of the flange plate professional production, the other end of the ring by a combination of throttle, transmission fluid when the convex surface of the flange national optimal use of the throttle ring , then take advantage of cutting-blind, a bit like the role of the valve off, it can be used to cut off when the valve is leaking. Relatively good sealing performance. The need for complete isolation of the system, are generally selected as a reliable means of isolation. Before and after the 8-word blind should have two shut-off valves, all in the closed state, the word blind swap eight states. Common heat exchanger cast and backup, and backup reactor cast convex surface of the flange of quality and quantity, nitrogen pipelines and process piping connections, and so on. Another significant feature is the identification, easy to install recognizable state. The main role played by blind character is completely cut off, like 100% reliable than a performance, they will not be the role of the misuse of the gate called the model forging forging forging, heat the billet after forging placed in fixed the forging die forging equipment on the. The basic process of forging die forging process: cutting, heating, pre-forging, the final forging, red skin, trimming, conditioning, shot. Common processes are upsetting, stretching, bending, punching, molding. Forging equipment commonly used equipment forging hammer forging, hot forging press, flat forging machine and friction presses and so on. More simply convex surface of the flange, forged flanges better quality, typically by forging production, fine crystal structure, high strength, and of course the price is expensive. Whether casting or forging flange flange flange are all common manufacturing method, the strength requirements needed to see the components used, if not high, the system can also be selected turning flange.
