The butt weld elbow dimension chart includes 90 degree& 45 degree long radius and short radius elbows.Butt weld elbow is a pipe fitting that is formed by butt weld the two ends of the pipe to form an elbow shape, which is used to change the direction of the pipe.

Butt weld elbows in butt weld elbow dimension chart can be divided into 90° and 45° elbows according to the angle, and can be divided into long radius and short radius elbows according to the radius.
