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.

Better lubricant control leads to better mandrel bends

September 11, 2007

By:

In an effort to reduce the need for cleaning bent tube, fabricator R & B Wagner analyzed its operations and decided to change from manual lubricant application to an automated system. The result was that its lubricant consumption dropped 70 percent. So little lubricant was left on the bent parts that the company eliminated the cleaning step.

8 FAQs about orbital FCAW

August 8, 2007

By:

Mechanized pipe GTAW was first introduced about 50 years ago for nuclear power plants, and then for steam-generation components and process piping. Orbital FCAW was developed to overcome the limitations of orbital GTAW for large-diameter, heavy-wall pipe. With orbital FCAW, deposition rates of 8 lbs./hr. are achievable. Just as a power saw is a tool for a carpenter, orbital welding systems are a productivity tool for the welder that empower him or her to weld faster and more accurately.

Tube bending

Constant radius or variable radius?

July 10, 2007

By:

While rotary draw bending is the mainstay of the tube bending industry, variable-radius bending is making some headway. Variable-radius bending offers many advantages, primarily more sophisticated bends and faster cycle times. However, it has limitations, too. A main one is that an initial bend must be a minimum of approximately 15 degrees.
