Blind character suggests that it is shaped like eight words, it is the blind end, the other end of the ring is made of a combination of throttle, transmission fluid when using the throttle ring plane flange, then use blind when cut, a bit like off valve action, 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 welded flange cast and backup, and backup reactor cast 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 a misuse of the valve flange forged flange is the best product in the mechanical properties of a product, its raw materials generally tube, then cut further after constantly beat to eliminate segregation in the ingot, porosity and other defects. Price and mechanical properties than normal casting flange high a grade. The tube and pipe flanges are connected to each other and the valve part is connected to the pipe end; Import is also useful in the apparatus on the flange for connection between the two devices are interconnected so that the tube and the tube parts, connected the pipe end. Is a subsidiary of pipeline accessories. Forged Flanges main materials are carbon steel, alloy steel, stainless steel. The main standards GB, electric marking material is guaranteed flanges, ANSI, DIN, JIS and so on. The main anti-corrosion treatment has oiled and galvanized. Forging flange pressure, temperature performance is better, generally applicable to high pressure and temperature of the working environment. [Henan] flange, flange material is guaranteed, provided by Hebei Hebei Cathay Cathay. Welcome to consult Hebei Cathay Pacific Pipeline Equipment Co.
