Tube and Pipe Fabrication Articles

The tube and pipe fabrication technology area covers sawing (band, circular, and friction) and other cutting processes, such as abrasive, flame, laser, oxyfuel, plasma, and waterjet. It also discusses forming processes, including bending and end forming. Finally, it includes a handful of miscellaneous processes, such as trimming, beveling, finning, grooving, threading, and spinning.

Electroslag cladding provides alternative to standard cladding techniques

August 25, 2015

By: ,

Cladding, often used in manufacturing or repair, is a good way to conserve an expensive alloy. Weld cladding techniques can be manual or automated. A conventional automated technique is submerged arc strip cladding (SASC), but this isn’t the only process. Electroslag strip cladding (ESSC) is a viable alternative.

Minimizing effort, maximizing distance

July 21, 2015

By:

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.

Orion Drilling Co. has rigs, will travel

July 16, 2015

By:

Before purchasing a 3-D CNC cutting system from HGG, oil rig builder Orion outsource quite a bit of its work. In addition to being at the mercy of its subcontractors’ lead times, Orion had to deal with their quality, which often wasn’t sufficient. The machine has been such a productivity enhance that Orion estimates the ROI period to be one year.

Top Fuel races are a dazzling sight, covering 1,000 feet in little more than 3 seconds. The drivers get the glory and the engines get the attention—they develop approximately 10,000 horsepower—but underneath the car’s exterior is a marvel of modern engineering: a tubular chassis that somehow holds together through 4G of acceleration during the race and the even harsher 5G of deceleration when it’s over.

Electric bender cuts lead times, scrap rate

March 12, 2015

By:

Former toolmaker Toolspec Manufacturing Co. has transitioned over the years to become a fabricator, and over the years acquired 14 hydraulic benders. The machines are capable but require lengthy tool changeovers, hours of programming time, and substantial expertise to maintain bend consistency. It recently invested in two all-electric machines, benders that don’t have these issues.
