What is a sweep elbow?

A sweep elbow is simply an elbow made out of a bent piece of pipe. There are short radius and long radius versions. To put this into context versus weld elbows, a short radius sweep elbow has a centerline of 3D (3 x the diameter of the elbow) whereas that is considered a long radius on a weld elbow.
