A pipe elbow is one kind of pipe fittings which can change the liquid or gas flowing direction in a piping system. It is mainly used to connect two pipes, sometimes called a “quarter bend”. Elbows are split into three groups, which define the distance over which they change direction. Commonly, according to the distance of direction changing, the elbows are divided into the following three kinds: Short Radius Elbow(SR Elbow), Long Radius Elbow(LR Elbow), Customized Radius Elbow.
As we known in the pipe fitting and elbow standard, the butt welding elbows commonly are 45°,90°,180°. But in the projects, sometimes the engineer or designer may use the elbows which degree are not the standard degree, such as 60°, 70°or others with such elbows, the flow direction in the piping system can be designed as per they need.
