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.

Getting a grip on tube bending

April 27, 2011

By:

A collet closer, commonly found on CNC or NC tube benders, serves an important role in the bending process. When quality is good, little attention is paid to its operation. When one or more quality parameters fall outside of acceptable limits, often the collet closer again is overlooked. A...

Get the slug out

January 31, 2011

By:

Punching a hole in a tube is one thing; getting the slug out is something else altogether. Even if most of the slugs exit without a problem, the occasional hanging slug can cause a serious problem. Two methods are mechanical force and air pressure.

Tube bending with no straights? No problem

November 1, 2010

By:

A Wisconsin tube shop invests in an unusual, freeform bending technology that can bend tube sections with no straight sections between bends. Different radii requires no tool changeouts or complex tooling setups. Instead, an operator changes the code in the controller.

The axis of safety

September 16, 2010

By:

A tube bender can be considered a collection of power presses and, as such, it needs more than just a few conventional barriers between the operator and the machine. Safety mats, interlocked switches, emergency-stop switches, and interlocked side plates are a few of the safety devices available to machine tool manufacturers.

Cold sawing turned inside out

September 10, 2010

By:

Cold sawing, widely used for cutting tubes, pipes, bars, and profiles for decades, has evolved steadily over time through advances in materials, coolants, coatings, tooth forms, and cemented carbides. However, new tube, pipe, bar, and profile materials are harder to cut than conventional materials, so some factors such as sawing speed and noise haven't improved much. A new machine and blade design has the potential to help fabricators substantially.

Feeding the process

July 9, 2010

By:

Whether a bending process starts with a cut length of tubular product or a coil, gravitational or torsional forces can lead to unwanted variations in the finished product. In the case of gravity, tube supports can counteract it; for torsion, it’s a matter of matching the coil’s output to the bender’s input.

Since its start as a supplier of a single fabricated item in 1936, Zeman Manufacturing Co. has expanded its fabricating services to include all manner of cutting, bending, end forming, and finishing processes. In response to growing competition from companies in low- cost-of-manufacturing countries, it took a journey down the lean path and became a nimbler company in the process.
