About Bending Rotation Angle

If the bending direction of a bend is different from the previous bend, the pipe piece must be rotated at a certain angle before bending to obtain the right bending direction. This angle at which you rotate the pipe piece is called the bending rotation angle. The bending rotation angle is shown in the following figure.

1. Pipe piece rotation by 180 degrees before the second bending

2. Bending direction
