Supply chain collaborates on bending project: Planning, cooperation keep project on schedule despite short time frameFaced with a daunting bending contract and a short timeframe, Rick Williams of Rockford Process Control (RPC) sought cooperation from a tubing supplier, bending machine manufacturer, and a tooling supplier at the beginning of the project. The information exchange enabled RPC and its supply chain partners to develop a process, deliver a bender, and engineer and manufacture tooling without the benefit of tubing samples.

All eyes on Dusseldorf: TUBE® expo hints at things to comeThe timing of the previous TUBE expo in Dusseldorf was nearly perfect. The industrialized economies were growing, oil was around $100 per barrel, and capacity utilization was healthy across the board. A few signs indicated trouble ahead, but it was a successful expo nonetheless. Now it is time for the 2010 show, and again the timing is good. Most of the industrialized countries have rebounded from the biggest financial crisis in 80 years, and many economists expect 2010 to be a big improvement over 2009. In addition, the tradeshow organizer has reported increased registration compared with the previous expo, and the TUBE exhibition space is sold out.

 |
Finding seemingly insignificant flaws Part II: Part II: Coil selection, equipment location, system implementationEddy current testing does more than detect product defects. When used with a proper monitoring system on a mill staffed by highly trained operators, it can help to optimize the mill's efficiency. The first part of this two-part article covers eddy current system principles.

Orbital welding for space program applications: Producing welds that withstand the rigors of deep spaceWelding applications in the aerospace industries demand high precision, a quality that can be entirely as low as possible. Automatic orbital welding is being used to help meet these requirements.

Brazing copper tubing: It's simpler than it seemsTorch brazing copper tubing is one of the most common–but widely misunderstood–joining processes. It's possible to make sound joints that are just as strong as the copper tube, easier to braze, and less expensive to produce. But first you have to know basic brazing concepts, including joint design, filler metal behavior, and metallurgy.

Pour me a mandrel: Bending tubes, pipes, and other forms with low-melting-point alloysTo reduce weight and cost for all types of products, design engineers often specify tubes and pipes with thinner walls instead of the previously used heavier-walled tubes and pipes. Shorter tube or pipe lengths also achieve the same objectives, but usually they require sharper or more complex bends. These designs make the tube bender's task more difficult.

Titanium trends: Energy demand, titanium demand grow hand-in-handElectricity demand grew an average of 15,000 megawatts per year from 1995 to 2006, and this trend will undoubtedly continue. The Energy Information Administration predicts that meeting future demands will require the equivalent of more than 20 new 500-MW power plants per year over the next 20 years or so. A critical component in power plant construction is titanium tubing, which is favored for its high strength and corrosion resistance.

Focusing on bent tubing: Making measurements using photogrammetryMeasuring the bends and straight sections of a bent tube can be tricky and time-consuming, especially if the tube has a large number of bends in several directions. Photogrammetry, also known as optical measurement, uses a booth equipped with several digital cameras to make a digital image of the part, allowing fast, easy measurements.

Minimizing wall thickness variation in seamless tubingAll mechanical steel tubing has some amount of wall thickness variation. Wall variation in welded tubing results from the strip manufacturing and tube welding processes. Seamless tube, which is created from a hot billet of solid steel, has wall variation that results from tooling wear, bearing and shaft variation, and normal hot-process variation. The wall thickness in seamless tubing varies in the cross section and along the tube's length.

TIG for titanium tubing: Success hinges on filler metal selection, cleanness, gas coverageAlthough titanium has a reputation for being difficult to weld, it doesn't have to be problematic. Paying close attention to filler metal selection, cleanness, and use of the shielding gas are three steps to successful GTAW on titanium tube and pipe.

Trends in offshore energy: Training, technology help overcome skill shortageThe welding industry is known for a persistent shortage of skilled workers, and the energy sector is no exception; meanwhile, offshore welding is getting more rigorous. The easiest-to-find oil sources were discovered long ago; with each passing year, energy companies go into harsher environments (deeper waters) to find petroleum and natural gas. Drilling into deeper waters means dealing with higher pressures and colder temperatures, and many companies have been switching too high-strength pipe, which tends to be more difficult to weld than common pipe.
