Years ago tube and pipe producers relied mainly on eddy current testing and ultrasonic testing for detecting short- and long-duration weld faults, respectively. These testing systems are still useful and in many cases required, but the spread of electronic technology has provided many more types of testing equipment for use on tube and pipe mills.

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.

Interviews with several TUBE exhibitors revealed that the energy industry remains the biggest driver in the tube and pipe industry. The opportunities aren’t just in oil and gas, but also wind and even nuclear, despite the Fukushima incident. Meanwhile, a few vendors have come up with machines and processes that reduce tube and pipe consumption and waste, helping the industry deal with fluctuating metals prices.

Editor Eric Lundin visited Gordon Branch, the guitarmaker featured on the cover of the June 2011 issue of TPJ, to see what Branch had come up with in the last few months. In addition to a new model, 33 1/3 Degree, made with round tube, Branch had developed a similar model made with tube shaped like an airfoil.

Artist and fabricator Philip Dees, who holds a bachelor’s degree in art and a master’s degree in fine art, has worked in metal fabrication and roll forming for nearly 30 years while pursuing a career as an artist. In addition to his drawings, paintings, and sculptures, Dees sees other opportunities for artistic expression, such as refurbishing an old house.

The essential tube and pipe production processes on a weld mill haven't changed much since the 1920s. Some new processes are available, such as laser welding, and the line speeds are faster, but much else hasn't changed. One factor that has undergone some change is how the weld bead, also known as scarf and a stringer, is handled. The conventional method was to wind it up as it came off the tube, but OD scarf choppers reduced operator exposure to this strand of red-hot, razor-sharp metal. Similcut has taken safety a step further by introducing a self-feeding OD chopper and wheelless, cantilevered ID chopper.

It wasn’t that long ago that Alessandro Volta built the first battery. In 1800 he made a stack of metal plates, alternating zinc and copper, with each pair separated by layers of cloth soaked in brine. Today’s batteries are more sophisticated but use the same principle to create electromotive...

Manuel Sarmiento went to a vocational school to learn to be a fender-and-body technician and to learn to paint cars. Fooling around with a plasma cutter one day, he cut out the shape of a hand and took it home to his wife. She loved it and encouraged him to experiment more. Years later he was successful enough as an artist that he quit his full-time job, and today his artwork supports him and his family.

Thefts. Car-jackings. Kidnappings. Assassinations. If you’re a high-profile political figure or wealthy executive doing business in a foreign country, especially one in which the division between rich and poor is vast, you’re vulnerable. In addition to having a security system at your home and a personal security detail that travels with you wherever you go, you need a vehicle that can protect you against an attack. Texas Armoring Corp., a fabricator in San Antonio, has been providing armored cars to foreign heads of state and corporate executives since it was founded in 1997.

It could be a dream come true or the latest scene in a long nightmare. Dow AgroSciences has developed a genetically engineered corn, named Enlist, to withstand herbicides containing 2,4-dichlorophenoxyacetic acid (2,4-D). The chemical was developed with the intention of helping to increase crop...

We’re still slogging through the jobless recovery, and while slowly falling unemployment took many by surprise in 2010 and 2011, I guess most of us have resigned ourselves to looking for reasons. There isn’t much else we can do. Before we look for reasons, let’s look at the trend. If we go...

When Tioga Pipe Supply Co. Inc. built a new facility in Easton, Penn., it leveraged its 60 years in business to design its new building. It planned the new facility, 150,000 sq. ft. under roof and 10 acres of outdoor storage area, around the use of side-loading lift trucks. The only drawback was occasional damage to the fork trucks' guide rollers, which Combilift eliminated when it designed a set of adjustable guide rollers specifically for Tioga.

In a recent blog post, my colleague Tim Heston described the need for the U.S. to develop an advanced manufacturing base with turn-on-a-dime flexibility. He called it a moral imperative, and I couldn’t agree more. The U.S. hasn’t lost its position as the world’s largest manufacturer, but...

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.

Don McNeeley, president and CEO of ChicagoTube & Iron, describes the big turning points in a company's inflection. For many companies, a point of inflection is the plateau between the company's youthful growth phase and the decline into old age, the point at which profibility slows. The winner of TPJ's 2012 Industry Award, Chicago Tube & Iron has a history of disrupting the growth-plateau-decline pattern.
