According to the radius of curvature, carbon steel elbows are divided into long radius(LR) elbows and short radius(SR) elbows. The long-radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the tube, ie R = 1.5D. A short-radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R = 1.0D. (D means the outside diameter, R is the radius of curvature. D can also be expressed in multiples.)
Carbon steel elbows are divided according to pressure rating, there are about 17 kinds, and the United States tube standard is the same, there are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80 , Sch100, Sch120, Sch140, Sch160, XXS, the most common of which are STD and XS.
The elbow of carbon steel is divided by the angle of the elbow, including 30deg elbows, 45deg elbows, 90deg elbows, 180deg elbows.
The production of carbon steel elbows is relatively simple and is mainly applied to pipeline systems with corrosive media. Elbows and flat rings can be made of different materials to reduce the cost of the elbows and improve performance. Its good performance advantages, can guarantee important use performance and operational contribution, widely used in thermal power, steel, smelting, cement, machinery, coal, mining, chemicals, ports and other industries.
