Stamping Carbon Steel Elbow
Carbon steel elbows are metal fittings that change the direction of the pipeline on carbon steel pipes. The connection methods are threaded and welded. According to the angle, there are three most commonly used ones: 45° and 90°180°. In addition, according to engineering needs, it also includes other abnormal angle elbows such as 60°. The elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The ways to connect with the pipe are: direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, etc. Other names: 90 degree elbow, right angle bend, love and bend, etc.
Carbon steel elbow English (Carbon steel elbow) is first classified according to its radius of curvature, which can be divided into long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature equal to 1.5 times the outside diameter of the tube, that is, R=1.5D. Short-radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R=1.0D. (D is the diameter of the elbow, R is the radius of curvature. D can also be expressed in multiples.) If divided by pressure level, there are about seventeen types, which are the same as the American pipe standards, including: Sch5s, Sch10s, Sch10 , Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, among which the most commonly used are STD and XS. According to the angle of the elbow, there are 45° elbow, 90° elbow and 180° elbow. Implementation standards include GB/T12459-2005, GB/T13401-2005, GB/T10752-1995, HG/T21635-1987, D-GD0219, etc.

Because stamping elbows have good overall performance, they are widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding and so on.
