When Cangzhou Bohai Pipe Co., Ltd. specializing in the production of 20 steel stamping elbow elbow welding, after heating will release carbide, carbide precipitation subjected to repeated heating, the release of carbide stamping elbow affects performance, reduce corrosion resistance and mechanical properties. These are on when using stamping elbow caveats 20 # carbon steel elbow, need to follow certain methods and use matters to ensure its good value and performance. Carbon steel elbow resistance of air, steam, water and other weak aggressive medium and acid, alkali, salt and other chemical etching medium corrosion of steel. After another welding bridge housing a variety of rod, the rod butt 20 # carbon steel elbow manufacturers, as well as welding and other special parts. New wear-resistant carbon steel elbow is a ceramic and metal organic combine to form a composite pipe, carbon steel elbow combination of high alumina hardness, chemical inertness and head there will be good quality assurance. Improve carbon steel elbow in reducing medium corrosion resistance, especially against chloride to localized corrosion. Improve the high temperature mechanical properties of austenitic stainless steel tee Increases strength and tempered carbon steel elbow stability study shows , Mo improve the corrosion resistance of carbon steel elbow in reducing media sales in the 20 # carbon steel elbow, mainly due to the anode molybdate inhibitor, the compound effects of Mo and Cr improve passivation of carbon steel elbow and the ability to re-passivation (passivation film repair capacity), increase the stability of the passive film, thus making the stainless steel has better corrosion resistance. Cangzhou Bohai Pipe Manufacturing Co., Ltd. 20 carbon steel elbow elbow, seamless elbow commonly used in pipe bent portion 180 20 # carbon steel elbow for changing the direction of the pipe. Commonly used with 45 ° elbow and 90 ° Elbow bend radius of about 1.0 times the pipe diameter is called short radius elbow;. is about 1.5 times the pipe diameter is called long radius bend in the pipe system layout, the general should choose long radius elbow connection, short radius bend is usually used in relatively compact piping installation position of the occasion or to reduce costs. When using a short radius elbow, the maximum working pressure is generally the same size should not exceed 0.8 times the long radius elbow. miter When the elbow is usually used for low pressure (design pressure S2.0MPA), on the water, and similar conditions are relatively mild fluid medium large pipeline. When a single change of direction miter bend angle is greater than 45, not for combustible medium pipes, or subjected to vibration, pressure pulsation and temperature fluctuations on alternating load line 4 times 20 # carbon steel elbow |.
