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.

Hautau Tube Cutoff Systems LLC turned the lathe concept on its head when it developed a machine that holds tube steady and uses tooling that orbits the workpiece. This concept, coupled with a handful of other innovations developed over the Hautau brothers’ professional careers, make these machines unique in how the perform recut operations.

Undertaking the challenge of tube fabrication

July 16, 2012 | By Dan Davis

The field of aerospace tube fabricating is one marked by difficult-to-form materials and very tight tolerances. As a result, not too many shops are involved in the business. Tube Specialties, Tempe, Ariz., however, has emerged as a go-to shop for this type of challenging work.

Elastomeric swaging

Looking for an alternative to conventional swaging?

July 2, 2012 | By Eric Lundin, Trish Harbaugh

A fluid-carrying line usually consists of a length of tube or pipe that has a fitting that is either attached at the end of the tube by a conventional swaging method or attached to the tube by welding. A little-known process, elastomeric swaging, bulge-forms the tube or pipe ends. Its niche is in small-diameter, heavy-wall applications that carry fluid under substantial pressure.

Editor Eric Lundin visited Gordon Branch, the guitarmaker featured on the cover of the June 2011 issue of TPJ, to see what Branch had come up with in the last few months. In addition to a new model, 33 1/3 Degree, made with round tube, Branch had developed a similar model made with tube shaped like an airfoil.

Fabricator reduces part handling, improves consistency with combination bender

April 11, 2012 | By Eric Lundin

Full Vision Inc., a manufacturer of components and equipment for the off-road industry, encountered a hurdle in manufacturing roll-over protection systems (ROPS) and falling-object protection structures (FOPS) for its customers. To make a ROPS or FOPS, it needed three machines or two setups on three machines. This led to too much part handling and more scrapping of parts than necessary. A combination rotary draw and push bender from Horn Machine Tool allows Full Vision to make a complete part with one setup on one machine, eliminating part handling and reducing scrap.

Assessing the arc

December 9, 2011 | By George Winton

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 Nicholas Maropis

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.

Fabricator leaves its competitors in the dust

July 20, 2011 | By Eric Lundin

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.
