Carbon steel elbows are metal fittings used to change the direction of carbon steel pipelines. The connection methods include threaded and welded connections. According to the angle, the most commonly used are 45°, 90°, and 180° elbows. Additionally, there are non-standard angle elbows such as 60° as needed for specific projects.
The materials for elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. The methods for connecting to pipes include direct welding (the most common method), flange connections, hot-melt connections, electrofusion connections, threaded connections, and socket connections.
Based on the manufacturing process, elbows can be divided into welded elbows, stamped elbows, pushed elbows, cast elbows, etc. Other names for elbows include 90-degree elbows, right angle elbows, and return bends.
