Welding Digest ►  Four New Products for the Metal Pipe and Tube Industry

This article informs of products that are designed to increase productivity for a variety of applications involving pipe and tube, including transporting, heating, cutting, and welding.

The metal pipe and tube manufacturing market, measured by revenue, is currently estimated at $12.4 billion, and this number is expected to increase by 2.7% (Ref. 1). The following four new products can help you meet the demands of this growing industry.

Induction System Offers Onsite Heating


Produced by Miller Electric Mfg. LLC the ArcReach® induction heating system (Fig. 1) achieves jobsite weld joint preheating and bakeout for construction and pipe applications, including refinery, petrochemical, power plant, shipyard, structural construction, and oil and gas. Offering a temperature maximum of 600°F (315°C), the heating system typically brings a joint to temperature in 20 min or less using electricity from heating tools placed on or around magnetic metal surfaces, such as iron or steel, to create currents in the metal. These currents pass through the workpiece and are converted to heat so the workpiece itself is the source of the heat, not the heating tools. The system is equipped with a heater that is used with air-cooled cables or quick wraps as heating tools, which enables contractors to insource preheating and bakeout by utilizing the welding power sources already on site. This eliminates the need for third-party contractors and provides complete control of the schedule. The induction heating system is also faster, safer, and less expensive than open-flame or resistance heating methods.

Pipe and Tube Cutting Software Unveils Updates

Developed by Hypertherm Inc., the updated Rotary Tube Pro™ 3 software (Fig. 2) showcases features and enhancements that facilitate the design and cutting of pipe and tube parts. Designed for machines with a rotary axis, the software simplifies common line cutting to allow operators to cut two or more parts so they share at least one common line with one another. This improves material utilization and consumable life. The software also covers costing for parts, nests, and jobs, including those associated with consumable wear, machine operation, labor, and electricity. Additionally, the software performs autoselect of material, which allows operators to enter basic material descriptions in the settings and automatically map the available materials. With this feature, operators do not need to separately pick a material and thickness once the tube size and wall thickness have been selected. Users with an active maintenance plan can upgrade to this software version at no additional charge.

Pneumatic In-Line Conveyor Achieves High Throughputs

Made by EXAIR Corp., the Line Vac™ in-line conveyor (Fig. 3) transports high volumes of material through ordinary pipe. It ejects a small amount of compressed air through the directed nozzle to produce a vacuum on one end with high output flows on the other. The conveying rate is easily controlled using a pressure regulator on the compressed air supply. The 2 ½ National Pipe Thread Taper (NPT) heavy-duty threaded conveyer features a large throat diameter that makes it possible to transport more material over longer vertical and horizontal lengths. Designed for industrial applications, it has a hardened alloy construction that helps prevent premature wear when moving abrasive or heavy materials (e.g., shot blast, tumbling media, and metal fittings). The conveyer is offered in seven sizes from 3/4 to 3 NPT to fit popular pipe sizes. Standard-duty models made from aluminum as well as 303 and 316 stainless steel are also offered in eleven sizes with or without threads.

Welding Machine/Generator Designed for Demanding Environments

Created by The Lincoln Electric Co., the Vantage® 441X welding machine/generator (Fig. 4) is equipped with a 41-hp, turbocharged Perkins® diesel engine and offers a 400-A, 100% duty cycle direct current output to meet the needs of demanding jobsite environments. The Tier 4 Final engine, which has an International Electrotechnical Commission rating, delivers the power necessary for running heavier electrodes in cold weather and high altitudes. It also showcases a rugged design with encapsulated ground-fault circuit interrupters, stainless steel paneling, strain-relief wiring, and potted PC boards. Additionally, the welding machine/generator performs shielded metal arc welding and features customized weld modes for carbon steel, aluminum, and stainless steel. For more advanced applications, it includes dedicated submerged arc welding and orbital pipe modes, along with synergic pulse capabilities for better arc performance in gas metal arc welding. It also comes standard with CrossLinc® technology, which enables precise voltage control at the arc without the use of an extra control cable. The welding machine/generator can be ordered as a standalone machine or in Ready-Pak® options that come assembled on heavy-duty trailers directly from the factory.
