In a piping system, a bend is a pipe fitting that changes the direction of the pipe. According to the Angle, there are 45° and 90°180° three most commonly used, and other abnormal Angle elbows such as 60° are also included according to engineering needs. Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, Carbon Steel, non-ferrous metals and plastics.

The methods of connection with the pipe are: direct welding (the most commonly used way) flange connection, thread connection and socket connection. According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow and so on. Other names: 90 degree bend, right Angle bend, etc
