Tube and Pipe Fabrication

The tube and pipe fabrication technology area covers sawing (band, circular, and friction) and other cutting processes, such as abrasive, flame, laser, oxyfuel, plasma, and waterjet. It also discusses forming processes, including bending and end forming. Finally, it includes a handful of miscellaneous processes, such as trimming, beveling, finning, grooving, threading, and spinning.

Bending nonround tubing

August 1, 2009 | By Bob Want

While bending round tube and pipe involves many variables and challenges, the difficulties in bending nonround shapes are more numerous and complicated. Among the most common shapes are square, rectangular, and oval (elliptical and flat-sided). None react to the bending force in the same way that round shapes do, so understanding how the material reacts is the first step in learning about bending nonrounds.
