Tube and Pipe Production Articles

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.

Improving flying cutoff operations, mill productivity

December 16, 2014

By:

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.

Tube producer opens doors to new markets, controls costs with laser welding

June 30, 2014

By:

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.

By:

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.

Cutoff choices for tube, pipe producers

December 2, 2013

By: ,

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.

Laser-based skelp edge inspection enhances quality control from the start

October 25, 2013

By:

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.

Souping up old draw benches

October 24, 2013

By:

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.

Know the chemistry, know the process, know the test

September 6, 2013

By:

For tube and pipe producers, testing the product on the mill is necessary, but not necessarily optimal. The line speed might be too slow, the mill might have some maintenance issues, and other factors can interfere with online testing. For these reasons, many supplement the online test with an offline test.

Using fiber lasers for stainless steel tube and pipe

July 19, 2013

By: , , ,

Tube and pipe producers have relied on GTAW and plasma for many decades, and CO2 lasers for more than a decade, but recently another choice has emerged: Fiber lasers. Relying on a solid fiber rather than a gas to generate the laser beam isn’t ideal for every material and wall thickness, but it will change the industry in a profound way.

Recycling overspray dust, related byproducts from thermal spray remetallizing operations

April 19, 2013

By:

The welding done in a tube or pipe mill ruins the galvanic or aluminum coating intended to keep the product corrosion-free, so remetallizing the weld seam is a common practice. Remetallizing creates a large amount of metal dust, which usually is considered a big nuisance and an expensive disposal headache, but in some cases it can be recycled for a profit.

Stretching, reducing on a tube or pipe mill

March 7, 2013

By:

The forge-welding process is one of the most efficient methods of making tube and pipe from 1/2 to 24 in. diameter, but it’s not limited to this range. An ERW mill’s capability can be expanded by adding a cold-stretch-reducing section, allowing it to make smaller diameters.

Fabricator rides new wave of interest in hydroforming

October 8, 2012

By:

Founded in 2003, American Hydoformers Inc. arrived on the scene a little too late to catch the first big wave of interest in hydroforming. A few automobile manufacturers had been oversold on the technology and were cautious to continue to convert parts to hydroforming, but AHI didn’t stumble and fall. Wise investments in equipment gave the company a unique and thriving position in the industry.
