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.

Filter bag, housing manufacturer finds faster cutting process for aluminum, carbon steel, stainless steel

November 22, 2016 | By Eric Lundin

When industrial filter and filter housing manufacturer Filter Technology Inc. had one too many late and substandard shipments of steel components, it took matters into its own hands and started cutting pipe and making plate components using a band saw and machining centers. Then its staff went to FABTECH and saw a Soitaab plasma machine with a bed for flat parts and chucks for pipe.

Civil War re-enactors take aim at metal fabrication

August 31, 2016 | By Eric Lundin

The members of Battery G, 2nd Illinois Light Artillery had two cannons, an old school bus, and many miles to cover to stage mock battles. A team of Civil War re-enactors, they had discarded their previous bus and needed to transform their new bus. They enlisted the help of the staff and students at Blackhawk Technical College (BTC), Janesville, Wis.

Forming a Marman bead

August 25, 2016

The Marman clamp, devised to secure two cylindrical surfaces end-to-end, has earned a unique place in tube fabrication. Although it’s not always easy to form, the Marman bead is a robust, airtight seal suitable for many applications, and is often used for diesel engine exhaust systems.

A novel approach to pipe welding automation

July 29, 2016 | By Soroush Karimzadeh

Pipe welding often requires frequent adjustments to changing conditions. Some changes are significant enough to make automation impractical. Today, though, collaborative robotics is helping to make pipe welding automation more flexible.

Fabricating long coils rather than short straights

July 11, 2016 | By Wynn H. Kearns

Most fabricators work with standard lengths of straight tube, but this isn’t the only possibility. Many alloys are available in coiled form, can lead to faster processing, better use of floor space, and increased material yields.

A big leap into big tube cutting

June 2, 2016 | By Tim Heston

If Richards Sheet Metal Works had taken the conventional path, it would have invested in a new flat-sheet cutting laser, especially considering its 5-kW workhorse was more than a decade old. But Richards isn’t a conventional metal fabricator. Today it has one of the largest tube cutting lasers in the country.

Advanced GMAW processes help in welding P91

May 26, 2016 | By Dan Hernandez, David Benson

Alloy P91 has excellent high-temperature strength and creep resistance, making it a favored alloy for piping systems for power boilers and other applications that work at elevated temperatures and pressures. The conventional welding processes, gas tungsten arc welding and shielded metal arc welding, do a good job on P91, but modified gas metal arc welding (GMAW) processes and flux-cored arc welding (FCAW) have deposition rates three to four times faster.

Tips on designing tubular parts for bending

April 18, 2016 | By Jon Canfield

Designing components, assemblies, and finished products is one thing; designing them for ease of manufacturability is something else altogether. Designers and engineers can use the tips in this article to design bent tubular parts to be as simple, and therefore as economical, as possible.

Heartthrob finds a less exhausting way to clean parts

April 18, 2016 | By Eric Lundin

Cleaning the inside of long, bent tubes is a chore, especially when it has to be done outdoors in inclement weather. Nobody knew this better than the staff at Heartthrob Exhaust Accessories, Litchfield, Minn., when they had to use a pressure washer outside during winter months. An ultrasonic cleaning machine brought the process indoors while making it faster and less labor intensive.
