Hollow Forgings

Hollows by Scot Forge

Scot Forge produces hollow tube-like forgings in diameters up to 90" with a 2" minimum wall thickness and up to 360" long or 300,000 lbs., in ferrous and non-ferrous materials.

Forging a hollow begins by making an upset preform, then punching a hole through the center. The workpiece is then drawn out over a mandrel to the specified length and O.D./I.D. configuration.

Hollows can be produced not only in a straight cylindrical shape, but with unlimited variations of O.D.s and I.D.s, including tapers. Because the inside diameter is forged into the part rather than bored from a solid bar, Scot Forge eliminates extra time, cost and material waste.

We also provide closed-end cylinders, both with and without flanges, in various wall thicknesses and cylinder end configurations to accommodate our customers' requirements.

Scot Forge saves production time and increases part strength for customers by producing hollow parts, such as flanged hollows, as single components rather than several components welded together.
