Cangzhou Bohai Pipe Co., Ltd. 20 # flange large forging large flange screw connection points (wire tapping) flange and welding flange low pressure small diameter wire flange, high pressure and low pressure are the use of large-diameter welded flange, different The thickness and diameter and the number of bolts of flange pressure is different according to different levels of pressure, there are different materials flange pad, the pad has a pad from the low pressure asbestos, asbestos mat to a high-pressure metal. 1. divided carbon material steel, cast steel, alloy steel, stainless steel, copper Taiyuan 20 # flange DN100, aluminum, plastic Taiyuan 20 # flange DN100, argon Ge Lek, ppc, etc. 2. production methods can be divided into forging flange, casting flanges, welded flanges, rolled flange (large number) 3. manufacturing standards can be divided into GB (Ministry of Chemical Industry, Petroleum standard, electricity standard), American Standard, the German standard, Japanese standard, the Russian standard and so on. large welding flange welding can be divided according to the different major and large welded flange welded flange Cangzhou Bohai Pipe Co., Ltd. specializing in the production of 20 # flange forging forming called the model forging forging, the blank is placed in a heated fixation on forging device of die forging. 1. The basic process of forging forging process: cutting, heating, pre-forging, the final forging, red skin, cutting, conditioning, shot. Common processes are upsetting, stretching 20 # Taiyuan flange DN100, bending, punching, molding. 2. forging equipment commonly used equipment forging hammer forging, hot forging presses, horizontal forging presses and other machines and friction. More simply, better quality forged flanges 20 # Taiyuan flange DN100, generally through forging production, fine crystal structure, high strength, and of course the price is expensive. Whether it is casting flange or flange forged flanges are all common manufacturing methods, see the strength requirements required to use part of, if not ask, you can also use the system turning flange. Overall 20 # flange, Taiyuan 20 # flange, Cangzhou Bohai Bohai Sea by Cangzhou Pipe Co., Ltd.. Cangzhou Bohai Tube Co., Ltd. (www.czbh628.com) (www.hbbh628.com) strong, credible, three-way, etc. Hebei Cangzhou accumulated a large number of loyal customers.
