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.

Structural tube on campus

January 13, 2004

Central Washington University in Ellensburg, Wash., is known for its strong science programs. "Flying Bridge," a structure designed by artist and sculptor Ed Carpenter, physically and metaphorically spans the biology and chemistry departments in the university's new Dean Science Building. Carpenter, who designed the bridge with engineering consultation from Peterson Structural Engineers Inc., teamed up with Albina Pipe Bending Co. Inc. to tackle the project's material bending and fabrication requirements.

Selecting a welding frequency

December 11, 2003

By:

Early power supplies for contact and induction welding for tube production, which were introduced in the 1950s, operated at 300 to 400 kHz. Modern power supplied, introduced in the 1990s, are variable from 200 to 400 kHz. While using any frequency in this range can produce acceptable welds for most applications, finite element analysis can be helpful for finding the optimal frequency for a particular gauge and material.
