An elbow is installed between two lengths of pipe (or tubing) to allow a change of direction, usually a 90° or 45° angle; 22.5° elbows are also available. The ends may be machined for butt welding, threaded (usually female) or socket. When the ends differ in size, it is known as a reducing (or reducer) elbow.
Elbows are categorized by design. The radius of a long-radius (LR) elbow is 1.5 times the pipe diameter. In a short-radius (SR) elbow, the radius equals the pipe diameter. Ninety-, 60- and 45-degree elbows are also available.
