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 based on engineering requirements. Elbow materials include cast iron, stainless steel, alloy steel, ductile iron, carbon steel, non-ferrous metals, and plastics. Connection methods to pipes include direct welding (the most common), flange connection, threaded connection, and socket welding. According to production methods, they can be categorized as welded elbows, forged elbows, cast elbows, etc. Elbows are commonly used pipe fittings for installation, facilitating connections at pipeline bend points. Other names include 90-degree elbows, right-angled bends, and ell bends. Applications: Connect two pipes with the same nominal diameter, allowing the pipeline to make a 90-degree turn. 1.
