HIGH QUALITY CARBON STEEL ELBOWS 45 Degree Elbow, 90 Degree Elbow and 180 Degree Elbow

Carbon steel elbow

Carbon steel elbow can be divided into long radius elbow and short radius elbow according to its curvature radius. A long radius elbow is the outer diameter of a pipe whose curvature radius is equal to 1.5 times, that is, R = 1.5D. Short radius elbow means that its curvature radius is equal to the outside diameter of the pipe, that is, R = 1.0D. (D is the diameter of elbow, R is the radius of curvature. D can also be expressed in multiples. There are about seventeen kinds of pipe standards, which are the same as those in the United States. They are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, among which STD and XS are the most commonly used.
