The tube and pipe production technology area encompasses mills and all of the equipment that makes a mill run successfully: tooling, welding units, nondestructive testers, bundlers, scarfing equipment, straighteners, scrap choppers, and washing systems.

A golf club shaft looks like an ordinary tube, but it’s not. Quite a bit of engineering goes into manufacturing the tube and drawing it so it has the optimal characteristics—lightweight without being flimsy and elastic enough to pack a wallop. Editor Eric Lundin interviewed Scott Cokeing, director of engineering and global quality True Temper Sports, about one of the company’s manufacturing processes, variable wall technology.

The adage “two heads are better than one” can be applied to tube and pipe mill monitoring systems. Monitoring the forming process is a good idea, and monitoring the welding process is too, but using a combination system that measures both yields additional benefits.

Taking all of the necessary parameters into consideration when designing a tube or pipe mill can be a big task, but it doesn’t have to be overwhelming. The main considerations include all of the cooling system capacity and location, the type of coolant, the filters and skimmers to be used, and local water quality. Making these decisions early, and incorporating them into the mill’s design, maximizes the cooling system’s efficiency.

Eddy current and ultrasonic testing are suitable for tube and pipe mills and have been used for weld seam flaw detection for decades, but a new process, thermography, is an alternative. By measuring the heat signature of the weld seam as it cools, it provides information about weld integrity at and below the surface.

Roll formers that want to branch out to welded profiles need to know about the main welding processes – GTAW, laser, and induction. This article compares and contrasts each process so roll formers can determine which is best for particular applications.

Accurate and reliable length and speed measurements are critical parameters that help tube and pipe producers increase yield, improve quality, and reduce production costs. The relentless improvement in electronic technology, accompanied by falling prices, have made laser-based measurement systems more capable and affordable than ever before.

Tube and pipe production is a capital-intensive process, but paying close attention to the efficiency of some of the lowest-cost items, specifically the consumables, can yield big benefits in productivity. At the cutoff, proper blade choice and optimizing the cutting depth are important first steps, but it’s also necessary to diagnose saw problems and—most important of all—develop a blade replacement strategy that minimizes mill downtime.

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.

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.

Like any mechanical system, a mill can run only as fast as its slowest component. Understanding the advantages and disadvantages of various cutoff systems is the first step in making sure the cutoff keeps up with the rest of the mill.

As demands for higher tensile steel increase, width consistency and edge quality are increasingly important because high-strength material does not form like soft grades of steel. Using a precise system for evaluating coil dimensions and edge quality is more important now than ever before.

Superior Tube Co. Inc., Collegeville, Pa., a fabricator that draws tubing for small-diameter applications, recently set about to improve material flow through its plant. Realizing that moving 60- and 70-year-old draw benches likely would damage the motors and motor controllers, which were the original equipment, the company developed a plan to upgrade the hardware at the same time. The result is a quantum leap in motor efficiency and monitoring capability.
