Elbow is a commonly used pipe fitting for connection in pipeline installation. It connects two pipes with the same or different nominal diameter to make the pipeline turn at a certain angle. Bending radius less than or equal to 1.5 times the pipe diameter belongs to elbow, and bending radius greater than 1.5 times the pipe diameter belongs to elbow. According to angle, there are 45 ° and 90 ° 180 ° which are the most commonly used. In addition, according to engineering needs, the materials of 60 ° elbow include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metal and plastic.
