In piping systems, elbows are fittings used to change the direction of the pipeline. By angle, there are three commonly used types: 45°, 90°, and 180°, along with other non-standard angles like 60° as needed by engineering. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics.
Connection methods with pipes include: direct welding (common method), flange connection, hot melt connection, electric melt connection, threaded connection, and socket welding connection, etc. Categorized by production process: welded elbow, stamping elbow, push fitting elbow, casting elbow, and socket welding elbow, etc. Other names: 90-degree elbow, right-angle bend, etc.
