In piping systems, elbows are fittings used to change the direction of the pipeline. They come in three common angles: 45°, 90°, and 180°, with additional non-standard angles like 60° available as needed for engineering purposes. Elbow materials include cast iron, stainless steel, alloy steel, ductile iron, carbon steel, non-ferrous metals, and plastics. Connection methods include direct welding (the most common), flange connection, threaded connection, and socket connection. According to production processes, they can be categorized as welded elbows, forged elbows, and cast elbows, among others. Elbows are commonly used pipe fittings for installation, serving as connections at pipeline bends. Other names include 90-degree elbows, right-angle bends, and ell bends. Uses: Connect two pipes with the same nominal diameter to allow the pipeline to turn 90 degrees. 1.
