The standard elbow is divided into long radius elbow and short radius elbow according to the radius of curvature. Long radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the pipe, that is, R = 1.5D

The short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is,R = D. in the formula, D is the diameter of the elbow and R is the radius of curvature. According to the pressure grade, there are about 17 kinds of pipe standards, which are the same as those in the United States :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.

According to the Angle of the elbow, there are 45° elbow, 90° elbow and 180° elbow. In this way, there are many kinds of elbow. When ordering, the order is often expressed as follows: such as "LRSTD90o8", indicating long radius, pressure grade is STD, 8" elbow of 90O; For example,"SRXS45o4" stands for short radius, pressure class XS,4 "elbow of 45O. The above is the general classification of elbow. Gb elbow
We have 90-degree boxes with 45-degree bends. The bending radius is on the standard. There are also long and short radius elbow.
