Hebei Steel Pipe Manufacturing Co., Ltd. Tianhui (www.tianhuigangguan.com) are located in Yanshan County, Hebei Cangzhou Port Industrial Park, Contact: Liu Xiaopeng called the model flange forging forging, heat the billet after forging placed in fixed the forging die forging equipment on the. A basic process of forging forging process: cutting, heating, pre-forging, the final forging, red skin, trimming, conditioning, shot. Common processes are upsetting, stretching, bending, punching, molding. 2 forging equipment commonly used equipment forging hammer forging, hot forging press, flat forging machine and friction presses and so on. More simply mounds flanges, forged flanges better quality, typically by forging production, fine crystal structure flange weight, 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. Flange is welded large diameter pipeline connecting the two devices, usually two pieces plus a fastening bolt flange, low plasticity its strength, it will become hard after adding an appropriate amount of carbon, plastic lower intensity increased. It may be necessary to connect a high resistance to withstand the kind Raffarin, compressive, torsional flange, shear strength. Welded flange easily obtained, manufacturing simple, low cost, widely used, but less rigid, and therefore not be used in chemical process piping systems and high supply and demand, flammable, explosive and high vacuum requirements, extremely hazardous occasions. Sealing surface with a flat and raised face. Butt welding flange consume more, can not withstand high temperature, high pressure, repeated bending and temperature fluctuations role.
