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.

Conveyor components manufacturer relies on inverse lathe

April 8, 2013

Mining equipment has to take a beating more so than most other types of industrial equipment. Constant exposure to heat, dust, dirt, and debris means that mining equipment has to be built to last. When the Goodman-Hewitt branch of Joy Global looked to upgrade the machines it uses to make conveyor components for this industry, it looked for a cutoff machine that would hold tight length and squareness tolerances for this severe environment. Its search led it to Hautau Tube Cutoff Systems Inc.

Tips for buying a second-hand bending machine

September 10, 2012

By: , ,

The second-hand market can be a good source for a used bender, but buyers must be careful. A thorough evaluation of the bender’s capabilities and condition is necessary before making a purchase. Because modern benders are complex and sophisticated, the evaluation is best carried out by the manufacturer, not the buyer. Another option is buying a reconditioned machine from the manufacturer. However, depending on the bending needs, a new bender might be the only viable option.

Fabricator trades bend-cut-bend-cut-bend-cut-weld-grind-polish-blend sequence for bend- bend-bend-polish sequence

September 7, 2012

By:

SF Tube Inc., a fabricator that does a substantial amount of bending, found itself facing a perfect storm—it had quite a bit of manual equipment, it often had to use two or three benders to make a single component, its bend-splice-weld-grind-polish-blend process for many components was too time-consuming, its shop floor was crowded with machines, and its niche as a specialty bending house meant it was positioned for future growth. A new bender, one that provides both rotary bending and roll bending, eliminated these hassles and has positioned the company to take advantage of growth opportunities.

Undertaking the challenge of tube fabrication

July 16, 2012

By:

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: ,

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.

Fabricator reduces part handling, improves consistency with combination bender

April 11, 2012

By:

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.

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.
