Irregular shaped elbow

An elbow is a pipe fitting that changes the direction of a pipeline. According to the angle, there are three most commonly used types: 45 °, 90 °, and 180 °. In addition, other special-shaped elbows such as 60 ° are also included according to engineering needs. The materials for elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. The methods of connecting with pipes include direct welding (the most commonly used method), flange connection, hot melt connection, electric melt connection, threaded connection, and socket connection
