Large-radius bends are used in many places, such as appliance handles and automobile components. For measuring large-radius bends, fabricators have at least three options: go/no-go fixtures, entering the bent part’s measurements into a CAD program and using it to calculate the radius, and a depth gauge.
Overlooking a small component on a tube or pipe mill—even something as seemingly insignificant as the roller bearings inside the inboard and outboard stands—can lead to excessive downtime. Learning the proper way to install and maintain these bearings can extend their service life and improve the mill’s uptime.
The main topic at the 2011 EDTR Roundtable conference in Wilmington, NC, was safety. Many of the issues involve high forces, metals in motion, and red-hot parts—in other words, topics relevant to any and all tube and pipe producers and fabricators. Editor Eric Lundin summarizes the main hazards and recommended practices for mitigating them.
