In piping systems, elbows are fittings used to change the direction of the pipeline. The most commonly used angles are 45°, 90°, and 180°, with other non-standard angles like 60° available based on specific engineering requirements.

Elbows can be made from a variety of materials including cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics.

The connection methods to pipes include: direct welding (the most common method), flange connections, hot-melt connections, electrofusion connections, threaded connections, and socket connections.

According to the manufacturing process, elbows can be classified into welded elbows, stamped elbows, pushed elbows, cast elbows, and butt-welded elbows. Other names for elbows include 90-degree elbows and right-angle bends.
