Dapre reyon an nan koub, li ka divize mwen nto long koudr radi ak koud radi kout . Reyon long reyon an refere a pliye a ki gen reyon nan deviation se egal a 1.5 fwa nan dyamèt ekstèn nan tib la (R = 1.5D). Radyo a koule kout refere a Bend la ki gen reyon nan koub egal a dyamèt tiyo (R = 1.0D). (D se dyamèt koud la; R se reyon an nan deviation)

According to the radius of curvature, it can be divided into long radius elbows and short radius elbow. The long radius bend refers to the bend whose radius of curvature is equal to 1.5 times of the outer diameter of the tube (R = 1.5D). The short radius bend refers to the bend whose radius of curvature is equal to pipe diameter (R = 1.0D). (D is the elbow diameter; R is the radius of curvature)
