Cathay Pacific Pipeline Equipment Co., Ltd. Hebei (www.hbgtgd.com) is located in Cangzhou, Hebei Cangzhou Cang Yanshan Wuliyao Hing Road Industrial Area, Contact: Liu blind character suggests that it is shaped like 8 characters special treatment convex surface flange It is the blind end, the other end is a combination of throttle ring, when the transmission fluid, use the throttle ring convex surface of the flange, then use blind when cut off a bit like the role of the valve, the valve which can When used to cut leaks. 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 for sale cheap investment convex surface of the flange, 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, the role will not be as iron gate misuse welded flanges, many customers doubt that iron welded flange The quality is better than forged welded flanges. In fact, the quality of iron welded flange weld quality and forged flange is the same, but in the end what iron welding flange does not have guaranteed quality and quantity convex surface of the flange, the flange is welded iron Material of the most insecure, because the general process, the density of iron welded flange is not a problem, but during the production process, iron welded flanges little rough for testing, so it is, After that produced, iron welded flange material is not guaranteed
