Tube & Pipe Bending Common Terminology

Tube is bent around a fixed radius die with a mandrel insert in to prevent it from collapsing during bending. The tube or pipe is clamped against the die and this is then rotated whilst the pressure die moves in a straight linear motion. This is the most common form of bending.

Tube Bending

Tube bending is a metal forming process that is used to shape pipes or tubing.

Bending machines take straight tube stock and create a shape involving single or multiple bends. This allows the tubing to be formed in any fashion to fit the application’s specific needs. Round tubes are typically used for tube bending, but square or rectangular tubes can also be bent in order to meet your specific needs.

Similarities Between Bending Round and Rectangular Tubing

When the curved parts are to be used in construction, it is imperative that the steel fabricator and the bender/roller communicate exactly how the parts are to be oriented. Are the square tubes rolled against one of the sides or off-axis? Are the rectangular tubes rolled against the strong axis or the weak axis? Or are they to be rolled off-axis? Equally important is whether or not these curved tubes are architecturally exposed (AESS).
