Detailed description of ASME B16.9 standard elbow

　　Elbows: Pipe fittings used to change the direction of pipelines. All elbows have a radius of curvature R ≤ 3D, with the most commonly used being long-radius elbows (R = 1.5D) and short-radius elbows (R = 1D). Common angles are 90°, 45°, and 180°. Reducing elbows are also used occasionally (i.e., connecting to a different diameter pipe while changing the pipeline direction). They are classified by connection type as: weld neck elbows, socket elbows, and threaded elbows. In export trade, different materials and different countries have their own standards, as detailed below:
