Angular Offset:

In these offsets, a traditional 90-degree elbow is combined with an elbow sector with an angle of less than 45 degrees, which allows a small deviation to be satisfied. It takes advantage of the possibility that a 90-degree elbow at the end of a tube can be rotated all around in the circumference of 360 degrees. To manufacture the offset, the elbow is rotated 90 degrees at an angle less than 45 degrees in any direction, and the elbow sector is used to return the pipe to the vertical or horizontal direction. This type of offset is very often employed to match pipes with small deviation.
