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.

It's not often that a tool as simple as a hand-held circular saw wins an award for its design, but it happened when Exact Pipe Tools Inc. submitted three models to Design Zentrum Nordrhein Westfalen, one of the oldest design institutes in Europe. The saw clamps to the pipe, so users are safer and cuts are straighter.

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.

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.

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.

Texas is known for two or three commodities, namely cattle, oil, and barbecue, but the state has plenty of manufacturing, too. It’s a good environment for a fabricator and an entrepreneur with the imagination to come up with new products and build prototypes, regardless of the industry or market. Devin Gerland, found of JackRabbit Manufacturing, is one such entrepreneur.

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.

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.

O’Neal Steel, founded in 1921 in Birmingham, Ala., originally was a fabrication shop, and the founder later added metal distribution to the company’s repertoire. Over the decades the business model changed, fabrication disappearing altogether at one point. Eventually the company resurrected its fabrication arm, but one thing has been a constant: The company’s small-town, close-knit, neighborly culture.

A typical bending machine process is feed-bend-feed-bend, or maybe feed-bend-feed- rotate-bend, until the feedstock is used up. However, this isn’t the end of the fabrication process, which includes a subsequent cutting step. The cut often means waste, especially for short-length parts, and the problem is compounded when the volume is high or the material is expensive. Read about how one bender manufacturer changed the process to feed-bend-separate-feed-rotate-bend-separate.

It’s no secret that Düsseldorf’s biennial tube and pipe expo, TUBE®, is a good way to gauge the industry’s health. The expo is 3 percent larger in 2014 than it was in 2012, and the exhibitors interviewed for this article expect good things from the industry in the coming year. These in-depth perspectives also revealed that upheaval in the U.S. energy industry is leading to changes that will have repercussions for decades.

Lean manufacturing may have once been little more than a buzzword, but it is way of life for many in the metal fabrication industry. Meanwhile, the pursuit of quality is as critical as ever. Conference facilitators and participants discussed how these can go hand-in-hand at the 2013 EDTR roundtable event, Lean Manufacturing and the Quality Imperative, Sept. 15-17, Silverton, Ore. The outcome was a series of stories and tips that any fabricator could use to run leaner and maintain a quality product.

Tube and pipe producers are familiar with ultrasonic testing (UT) which, as the name implies, uses high-frequency sound waves to find discontinuities in tube and pipe. While conventional UT is effective for testing raw materials with simple shapes—round tubing, rectangular billet, and rectangular plate—complex shapes such as castings and assemblies need something more. Phased-array ultrasonic testing (PAUT) gets the job done.
