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. Elbows can be categorized by production process as welded elbows, forged elbows, cast elbows, etc. They are commonly used pipe fittings for connections at pipeline 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. Material types include carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, asphalt, and ppc. 2. Manufacturing methods include extrusion, forging, casting, etc. 3. Manufacturing standards include national standards, electrical standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc.
