Method for Fabricating Elbows for Pipeline Trays

The principal methods of hot working are extrusion, drawing, forging and rolling. Rolling is the most extensive employed forming process, though some limitations may apply to the process. 1), after which the plate is rolled into a cylindrical shape and, the elbow segments 12a, 14a, 14b are cut out according to the pattern.
