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.

Is your bend good enough?

July 13, 2004

By:

Bending tube or pipe so the finished product conforms to one of two bending standards can help to reduce rejects and improve relations between fabricators and their customers. The standards can facilitate the use of bending terms, and promote an understanding of bending tolerances and acceptable defects before starting a bending project.
