Tube and Pipe Fabrication Articles

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.

By:

Large-radius bends are used in many places, such as appliance handles and automobile components. For measuring large-radius bends, fabricators have at least three options: go/no-go fixtures, entering the bent part’s measurements into a CAD program and using it to calculate the radius, and a depth gauge.

Using ultrasonic energy for drawing tube

October 20, 2011

By:

In conventional metalforming operations, the main way to reduce friction between the tooling and the workpiece is to apply a lubricant. Another supplementary method, which has been used for decades, is to introduce ultrasonic energy to the tooling, resulting in microscopic, high-frequency vibrations that reduce friction and improve surface finish.

By:

It wasn't that long ago that Joe Fabiani decided to make a custom exhaust system for his Porsche. A member of the Porsche Club of America (PCA) and racing enthusiast, he soon found himself making exhaust systems for fellow PCA members. That led to founding a company, FabSpeed Motorsports Inc., which initially relied on outsourcing for nearly all of the fabricating. Fabiani recently opened a new division, FabSpeed Precision Services, and invested nearly $1 million in equipment in the new division to eliminate outsourcing.

Getting a grip on tube bending

April 27, 2011

By:

A collet closer, commonly found on CNC or NC tube benders, serves an important role in the bending process. When quality is good, little attention is paid to its operation. When one or more quality parameters fall outside of acceptable limits, often the collet closer again is overlooked. A...
