According to its radius of curvature, it can be classified into log-radius elbow and short-radius elbow. Log-radius elbow refers to that its radius of curvature is equivalent to 1.5 times of the outer diameter of the tube, i.e. R=1.5D; short-radius elbow refers to that its radius of curvature is equivalent to the outer diameter of the tube, i.e. R=1.0D. (D is the diameter of the elbow, and R is the radius of curvature.)
According to the pressure rating (the same as the American pipe standards), there are about 17 types of pipes, including Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;Sch80, SCH100, Sch120, Sch140, Sch160, XXS. Wherein, STD and XS are the most commonly used.
