Cangzhou Bohai Pipe Manufacturing Co., Ltd. 20 carbon steel elbow heat simmer elbow, also called IF Bend, its production process belong to the scope of thermal expansion. Process is this: after the straight pipe cutting, pipe pushing machine put through an induction loop in the pipe section to be bent, with mechanical boom head stuck pipe, 20 # carbon steel elbow DN500, through the induction circle IF current into the heating pipe, when the pipe temperature rises to a plastic state, in the back-end mechanical pipe thrust forward, were bending, bending pipe portion out immediately with coolant, so while heating forward, side bend system, while cooling, constantly bending the elbow out. Heat simmer elbow mainly used for construction circular steel structure, tunnel supports, curved roof beams, subway project, aluminum doors and windows, ceiling, cylindrical package within the skeleton, balcony handrails, shower door, the production line track, fitness equipment and other industries . Cangzhou Bohai Pipe Co., Ltd. 20 carbon steel elbow manufacturers to improve the stamping and welding elbow corrosion resistance, due to increase in the production of an appropriate amount of stability elements Ti, Nb, Mo, etc., welding stamping elbow better than the chrome. When using the same type of chromium stainless steel stamping elbow, 20 # carbon steel elbow, should be tempered after more than 200 ℃ preheating and soldering 800 ℃ or the. If you can not heat treated weldments, 20 # carbon steel elbow DN800, it should be used chrome-nickel stainless steel stamping elbow. Stamping elbow with good corrosion resistance and oxidation resistance, good features to facilitate their use and promotion in different fields, widely used in chemical, fertilizer, petroleum, medical machinery. 20 # carbon steel elbow DN150_ Cangzhou Bohai (certified) _20 # carbon steel elbow pipe provided by the Cangzhou Bohai Company.
