There are several types of carbon steel elbows
Classification of carbon steel elbow: The curvature radius of carbon steel elbow can be divided into long radius elbow and short radius elbow. The long radius refers to the fact that the radius of curvature of the carbon steel elbow is 1.5 times the outer diameter of the pipe, which is R=1.5D. The short radius refers to the radius of curvature of the carbon steel elbow is the length of the outer diameter of the pipe, which is R=1.0D. (Where D is the diameter and R is the radius of curvature)
According to the pressure grade can be divided into more than ten kinds, the bending standard used in our country and the United States is one version, they are: Sch10s, Sch5s, Sch10, Sch20, Sch30, Sch40, STD, Sch60, Sch100, XS; Sch80, Sch120, Sch160, Sch140, XXS, among which STD and XS are more commonly used. According to the Angle of carbon steel bend, there are 45 degrees, 60 degrees, 90 degrees and 180 degrees. Its executive standards are GB/T13401-2005, GB/T12459-2005, HG/T21635-1987, D-GD0219 and other standards.
According to the production method of carbon steel elbow can be divided into pushing carbon steel elbow, pressing carbon steel elbow, forging carbon steel elbow, casting carbon steel elbow and so on.
According to manufacturing standards, it can be divided into GB carbon steel elbow, electric carbon steel elbow, ship carbon steel elbow, American carbon steel elbow, Japanese carbon steel elbow and so on.
According to different shapes, it can be divided into reduced carbon steel elbow, flange carbon steel elbow, socket carbon steel elbow, butt welding carbon steel elbow, push carbon steel elbow, stamping carbon steel elbow, etc.
