Elbow

Elbow, which is formed by stamping a flat piece of the same material as the pipe into a semi-circular shape, and then welding the two semi-circular pieces together to create the final product. Due to varying welding standards for different types of pipelines, the semi-finished products are typically shipped with spot welds fixed in pairs, and the welding is done on-site according to the pipeline weld grade, hence also known as a two-piece welded elbow.
