Best coolant practices make perfect

May 28, 2015

By:

Taking all of the necessary parameters into consideration when designing a tube or pipe mill can be a big task, but it doesn’t have to be overwhelming. The main considerations include all of the cooling system capacity and location, the type of coolant, the filters and skimmers to be used, and local water quality. Making these decisions early, and incorporating them into the mill’s design, maximizes the cooling system’s efficiency.

Turning to milling for weld preps

May 26, 2015

By:

Preparing tube or pipe ends for welding with a portable tool is one way to get the job done, but for complex end forms and high-volume work, a stationary beveling machine is the way to go.

Measuring weld heat to evaluate weld integrity

May 14, 2015

By:

Eddy current and ultrasonic testing are suitable for tube and pipe mills and have been used for weld seam flaw detection for decades, but a new process, thermography, is an alternative. By measuring the heat signature of the weld seam as it cools, it provides information about weld integrity at and below the surface.

Choosing a welding process for tubular profiles

May 14, 2015

By:

Roll formers that want to branch out to welded profiles need to know about the main welding processes – GTAW, laser, and induction. This article compares and contrasts each process so roll formers can determine which is best for particular applications.

Heat it where you need it

May 5, 2015

By:

Before Thom Shelow founded Superior Joining Technologies Inc., he did quite a variety of welding, but his welding experience wasn’t the only asset he used to make the business a success. He keeps an open mind and is always ready to analyze new ideas, new concepts, and new technologies. “That’s the way we’ve always done it” doesn’t prevail at SJTI.

Getting a grip

April 24, 2015

By: ,

Setting the grip die securely in rotary draw bending requires close attention to three factors: the pressure exerted by the machine, the contact area, and the material’s coefficient of friction.

Reaping rewards with precision laser cutting

April 8, 2015

By:

In 1973 full-time farmer Mike Van Mill tried his hand at building a grain wagon for a neighboring farmer, and he has been at it full-time since incorporating Brent Industries a few years later. Now the operations manager for Unverferth Mfg., Shell Rock, Iowa, Van Mill is part of a team that manufactures implements under the Brent brand name. The staff runs the facility like a savvy farmer runs a farm, always looking for a better way but proceeding cautiously. A sheet laser purchased in the early 2000s led to a tube laser purchased in 2014.

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.

Handling structural steel, one truckload at a time

March 5, 2015

By:

For structural fabrication-and-construction companies, efficiency in logistics is vital. A typical column, beam, truss or joist is handled three times—first to a storage yard, then to a staging area, and finally to the semitrailer. However, this isn’t the only way to do it. Reinicke Athens Inc. recently invested in a straddle carrier from Combilift Ltd. Instead of moving one part at a time, the truck lifts and moves an entire load a time, cutting its trailer-loading time from up to 8 man-hours to as little as 30 minutes.

Using laser velocimeters to improve tube and pipe production

February 4, 2015

By:

Accurate and reliable length and speed measurements are critical parameters that help tube and pipe producers increase yield, improve quality, and reduce production costs. The relentless improvement in electronic technology, accompanied by falling prices, have made laser-based measurement systems more capable and affordable than ever before.

Developing a national, international bending standard for tube and pipe

January 23, 2015

By:

An update from an article that ran in the September 2013 TPJ, this column describes a research project intended to help eliminate trial-and-error setups, conserve programmers’ time, and help get products to market faster by helping everyone involved in a bending project home in on the optimal bending process before getting started.

Using continuous plasma for cleaning, surface activation of tube, pipe

January 21, 2015

By: ,

When fabricators need to remove lubricants or corrosion inhibitors from tube or pipe, they have no shortage of choices, both mechanical and chemical. However, they have a third option: Thermal. The intense heat developed in a plasma cleaning processes makes greases, oils, and contaminants inert.
