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-weld connection. Elbows can be categorized by production process as welded elbows, forged elbows, cast elbows, etc. They are commonly used pipe fittings for connections at pipe bends. Other names include 90-degree elbows, right-angle bends, and ell bends. Their purpose is to connect two pipes with the same nominal diameter, allowing the pipeline to make a 90-degree turn. 1. Carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, asphalt, ppc, and others are classified by material. 2. They can be divided into extrusion, stamping, forging, casting, and other manufacturing methods. 3. They can be categorized by manufacturing standards such as national standards, electrical standards, water standards, American standards, German standards, Japanese standards, Russian standards, and others.
