Bending tubular parts for the aerospace industry isn’t easy. OEMs continue to push the envelope, designing increasingly complex parts made from pricey materials. Fabricators are under continuous pressure to improve their capabilities, turn orders around faster, and minimize scrap. To that end, SL Engineering recently invested in a second all-electric bender from Unison.

For tube and pipe applications, laser vision systems are commonly used for seam tracking on the mill, but they are useful for many more applications—such as edge bevel measurement; strip width measurement and centering verification; mill process control; and coating control. For pipeline construction, they can verify the integrity of end face bevels and weld bead profile measurements.

When Bob Burns, owner of Aero Bending Co., Palmdale, Calif., moved his company to a new and bigger location, he considered adding to the company’s fleet of benders. However, a number of bending machine operators often lined up to measure bent components, creating a bottleneck. Changing to an optical inspection system cleared this bottleneck.

When Dave Milo set out to build a portable hardbanding unit, the former trucking company owner knew little about welding and nothing about hardbanding. After updating the hardbanding unit design a few times with consulting help from Lincoln Electric, Milo thinks he’s ready to change direction. Rather than providing hardbanding services, his goal is to sell hardbanding machines.

BSS Industrial, a plumbing and heating products distributor, was accustomed to using slings affixed to its fork lifts to lift tube bundles from truck beds. The drawback was that on occasion the load would swing, creating a tipping risk for the lift truck. Lift truck manufacturer Combilift developed a truck with standard-length forks for placing and picking inventory, and a longer set of forks for lifting tube bundles from the delivery vehicle’s bed.

A niche tube producer that formerly used GTAW exclusively, Esta Rohr began changing over to laser welding in 2005. The change is now complete, with substantial changes. The company has reduced its number tube production lines from five to three, but its output has increased tremendously. Meanwhile, laser welding has allowed it to cut some costs, helping its products compete against others.

Native Texan and farmer Aggie Devin Gerland earned a degree in agricultural engineering and took a succession of engineering positions in and around Bryan, Texas. Now an entrepreneur with his own fabrication shop, Gerland is putting his farming and ranching experience to work, developing his own line of farm implements.

The manufacturing standards for manufacturing and fabricating tube and pipe are continuously on the rise as OEMs demand tighter tolerances and ever-greater dimensional consistency. Keeping up with these trends is a matter of keeping up with the technologies available to monitor processes and measure tubular products.

For many, ideas such as green and sustainability are synonymous with recycling, but recycling is just one small part of doing things in a greener way. Minimizing the consumption that later needs to be recycled (waste) is an important aspect, too. Among tube and pipe fabricators, one area that can yield big benefits is lubricant consumption.

The welders at JATCO Environmental Inc., a manufacturer of steam-to-liquids condensers for natural gas extraction, had a problem with striking and maintaining a good arc. When the company switched from a rectifier-based unit to an inverter-based unit, the welders found that the arc starts and weld characteristics were greatly improved.

Freedman Seating Co., founded in the late 19th century, originally manufactured seat cushions for horse-drawn buggies. As gasoline engines displaced animal power, Freedman adapted and today uses the latest technologies, such as CNC tube benders and a laser cutting machine, to stay current with trends in transportation.

Properly setting up the tooling on a tube or pipe bender can be a straightforward process, but misunderstandings and shortcuts can lead to poor setups. The wiper die’s rake angle is one such setting. Operators should beware that setting the tool to a specific gap at its trailing edge can lead to inconsistent setups.

Prototyping a roll formed profile doesn’t have to be done in the conventional way, with hardened tooling and short runs made from long strips of material (or coil). American Roll Form uses butt-welded strips of steel, fed into a roll former outfitted with soft tooling, to prototype roll-formed sections. It uses a few other strategies that substantially reduce prototyping cost and lead-time.
