Tube and Pipe Fabrication

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.

Coax Facts

January 1, 2009 | By George Winton

Continuous improvement and statistical process control are useful,time-tested techniques—they have been used since the 1950s—buttheir use must be tailored to specific applications. For example, atypical manufacturing metric is parts per minute, but many rollformers should measure feet per minute. This and other tips can helproll formers accurately evaluate their productivity and measure theimpact of process improvements.

Teaching an old piercing mill new tricks

December 2, 2008 | By Albert Klimas

Many seamless tube producers in North America use cross-roll piercing mills built in the 1950s that were based on designs from the1930s. While it would be advantageous to replace such aged equipment, that isn't always necessary. A minor equipment upgrade can do wonders. Improving the bar steadiers—the devices that hold the mandrel the steady as the pipe exits the mill—can greatly improve the mill's output and reduce the pipe's wall thickness variation.

Waste not, want not

November 25, 2008 | By Lonnie McGrew

For many bending applications, it is common practice to determine the necessary length of tube, run a few samples, make some minor adjustments, and then start production runs. The problem is that the initial evaluation may have been based on safe, by-the-book estimates and calculations. Re-evaluating a bending project might yield substantial material savings.

Serpentine Bender

Serpentine bending in production

November 25, 2008 | By George Winton

Bending serpentine profiles—successive 180-degree bends, which typically are used in refrigeration systems—can be a challenge. By their nature, they tend to cause interference among the various bend dies, and they can be difficult to handle. Good planning in selecting a bender, planning the process, and paying close attention to infeed and outfeed options, can help make a serpentine project successful.
