180° Stainless Steel Elbow For The Connection At The Bend Of The Pipeline
In piping systems, elbows are fittings used to change the direction of the pipeline. The most commonly used angles are 45°, 90°, and 180°, with other non-standard angles like 60° available based on specific engineering requirements.
Elbows can be made from a variety of materials including cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics.
The connection methods to pipes include: direct welding (the most common method), flange connections, hot-melt connections, electrofusion connections, threaded connections, and socket connections.
According to the manufacturing process, elbows can be classified into welded elbows, stamped elbows, pushed elbows, cast elbows, and butt-welded elbows. Other names for elbows include 90-degree elbows and right-angle bends.
