The basic process of Cangzhou Bohai pipe Professional production of 20 # carbon steel elbow elbow is: First welding a polygonal cross-sectional polygonal ring shell or multi-row fan shell closed at both ends, the internal pressure washed over medium after Shi less pressure, under pressure, including the role of polygonal cross-section by becoming round, eventually becoming a circular ring shells. If necessary, a circular ring shell can be cut four or six 90 ○ 60 ○ elbow elbow elbow or other specifications, the process for the manufacture of elbow and elbow in diameter than the inner diameter of any size greater than 1.5 Large elbow 20 # carbon steel elbow, is an ideal method for the manufacture of large carbon steel elbow. Cangzhou Bohai Pipe Manufacturing Co., Ltd. 20 carbon steel elbow elbow, seamless elbow commonly used in the curved part of the pipeline, to change the direction of the pipe. Commonly used 45 ° elbow and 90 ° elbow bending radius of about pipe 1.0 times the outer diameter called short radius elbow; approximately 1.5 times the pipe diameter is called long radius elbow 20 # carbon steel elbow supply pipeline system layout, the general should choose long radius elbow connection. 20 # carbon steel elbow wholesale, short radius bends in the piping is usually more compact installation location or occasion in order to reduce costs. When using a short radius elbow, the maximum working pressure is generally not more than the same specification long radius elbows 0 .8 times. mitered elbow usually used for low pressure (design pressure S2.0MPA), on the water, and similar conditions are relatively mild fluid medium, large size pipes. When a single change in the direction of the miter bend angle is greater than 45, should not for toxic and combustible medium piping, or withstand vibration, pressure pulsation and temperature changes due to the alternating load pipeline. 20 # carbon steel elbow wholesale, Cangzhou Bohai (certified), 20 # carbon steel elbow by Cangzhou Bohai Fittings Limited.
