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.

To 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.

The main component in any off-road sport vehicle is the frame. Frames for mass-produced vehicles usually are stamped and welded. These are suitable for most drivers' needs, but for intense off-road driving and competitions, a sturdier frame is necessary.

Tube and pipe can be notched with a variety of tools and machines, from saws to plasma cutters. For the hobbyist, the job shop, and the manufacturer, the most common machine tools used for making weld joints are the hole saw, the abrasive-belt notcher, and the end mill notcher.

Who cares about scarfing tools? There are more important things in life. When the beauty pageant contestant is asked what problem she would like to solve, she's more likely to answer "I'd like to establish world peace" than "I wish I could find ways to help scarfing tools last longer."

The phrase "obstructed view" is probably most connected with older sports stadiums. For example, at Wrigley Field in Chicago, depending on where your seat is, watching Sammy Sosa in action in right field might be replaced by a view of a rusting steel girder.

Any manufacturing process that goes awry can result in waste in many forms, both obvious and hidden. A simple project in which tube is cut, bent, formed, and welded can result in large amounts of wasted money and time if one of the processes goes wrong.

The roar of the crowd, the shouts of the umpire, the crack of the bat hitting the ball—these are the unmistakable sounds of a baseball game. Over the last few decades, however, one of those sounds has changed; now the bat tends to make a distinctive, resonating ping. It's the sound of aluminum rather than wood making contact with the ball.

Torch 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.

Tube fabricators all over the country are starting to see some major benefits from new coating technology. Many coatings-both those that are time-proven and new ones just hitting the market-can provide many benefits for many tube fabrication processes, including extended tooling life, better finished parts, and less stress on machinery.

It drives right over nearly every obstacle in its path and splits nearly every eardrum in its vicinity. It's supercharged, oversized, and extraordinary. It stands more than 10 feet tall, develops more than 1,500 horsepower, and can leap over a 727 jet airliner in a single bound.

Hundreds of types of machined end connectors are used to transmit fluid in fabricated tube and hose assemblies. In recent years manufacturers and end users of these connectors have been developing new methods and processes that eliminate machined connectors and the associated joining operation. Eliminating connectors and joining operations can help save both money and time.

Band sawing is the starting point for many tube and pipe fabricating operations, and it can help determine the throughput and profitability of your whole shop. Maximizing the productivity of tube or pipe cutoff requires a coordinated approach to saw blades, sawing machines, and your cutoff process.
