Flange manufacturers often use ring rolling because it reduces material waste and creates a stronger forged structure compared with some traditional production methods. The process is suitable for pipe flanges, welding neck flanges, pressure vessel flanges and heavy-duty connection rings.
The machine works by placing a heated ring blank between the rolling wheel and mandrel. As the wall thickness is reduced, the ring diameter increases. Support rollers help maintain the ring shape during expansion.
A hydraulic ring rolling machine is suitable for carbon steel, alloy steel, stainless steel and other forgeable materials. The final configuration depends on ring diameter, ring width, production capacity and material specification.
For flange production, buyers should consider the maximum outside diameter, roller width, motor power, productivity and tooling requirements. A suitable machine can help improve output, reduce machining allowance and support repeatable ring quality.
If your workshop produces flanges or similar circular forgings, a hydraulic ring rolling machine can be an effective investment for improving production efficiency.
