| Abstract: | This paper introduces a novel dieless hydrobulging technology of elbow used in large-scaled pipeline system. A Q235A elbow with thickness of 3.0mm, cross section diameter of 531.0mm, curved radius of 1310.0mm and angle of 45.00 is obtained successfully from initial welded fan-shaped ring shells with hexagon cross section till approxmately 2.5MPa hydraulic pressure.Experiments applying dieless hydrobulging to manufacture elbow is simple, low-cost and feasible. |
