TUBE 2014 85 years of NDT test systems from MAC
nondestructive test instruments and systems for the metals industry, Magnetic Analysis Corp. will be featuring its newest ultrasonic, eddy current, and flux leakage inspection systems for tube manufacturers at stand 6G40 in Hall 6 at Tube 2014. A demonstration eddy current 50mm Rotary tester will be on display in the booth. Designed to detect long, continuous, seam type defects in tube and bar, MAC’s Rotomac® Z unit will be capable of rotating at 12,000 rpm with 4 test channels. The higher rpm allows faster throughput speeds on the production line, and the new design also provides greater convenience such as shorter setup time, and quicker and easier adjustments for different size product. Building on the outstanding success of MAC’s Echomac® Rotary ultrasonic testers, the company will also be featuring a new Spinning Tube ultrasonic test system at Tube 2014. This system features a unique APC (Automatic Pitch Control) transducer carrier which contains the water couplant and

follows and adjusts to the pitch of the tube as it rotates through the tester. This allows testing of a large range of pipe sizes, including large diameters, with minimal transducer adjustments, if any, during size changeovers. Further, because the transducers are under the pipe, no tight fitting glands or shoes are needed, resulting in lower water circulation requirements, fewer wear components and virtually no changes required to the basic water tank on size changeover. This Spinning Tube transducer system
can also be used for testing tube ends as well as for a retrofit or upgrade of existing installations. MAC will also be exhibiting the Xiris laser based weld inspection system. Information will also be available
on test systems using a combination of more than one type of test technology, a requirement to meet many of today’s stringent test standards such as API and ASTM. Echomac® ultrasonic testers combined with either MultiMac® eddy current or MAC’s Rotoflux® flux leakage technology can meet
these standards. At the same time both the ultrasonic and flux leakage systems are capable of testing to 5% defect levels on the OD and ID of tubular products. Because MAC is one of the few companies that can offer all of these technologies, the systems can be fully integrated, providing operators with a consistent look and feel as well as enabling combined defect reporting. These testers can easily be combined into complete, automated test systems including triple pinch benches to maintain accurate positioning, standard and custom conveyors, markers, sorters, demagnetizers, water circulation systems for ultrasonic test applications, and sophisticated controls, all designed by MAC. Typical system applications include testing welded and stainless tube, automotive tube, OCTG (Oil Country Tubular Goods), heat exchanger and duplex tube, among others. MAC’s knowledgeable field staff will provide information in multiple languages on all of Mac’s products.

Laser surface velocimeters LSV 1000/2000
Zumbach Electronics presents new, high-tech length and speed measuring gauges. Precision speed and length measurements are critical for optimization of continuous or quasi-continuous production processes. Proper utilization of these measurements can lead to lower production costs and higher product quality. The ideal sensor must exceed traditional contact encoder performance, increasing reliability and accuracy while minimizing maintenance requirements and material yield. The LSV Laser Surface
Velocimeters have been designed as the ideal next generation sensors for non-contact length and speed measurement. They provide precise length and velocity data quickly and reliably for both process control and cut-to-length applications. The LSV 1000/2000 measure reliably on almost any solid surface, whether controlling processes utilizing carbon steel, shiny aluminium or oily sheets, or producing round wire and cable, or manufacturing paper, cardboard or tissue. The main features, benefits and advantages are as follows:- • Zero speed, direction detection (model LSV 2000 only)
• Reduced operating and maintenance costs
• Attractive ROI, fast payback • All-in-one system, easy integration into production processes and control environments
• Easy to operate and no re- calibration required
• Visible laser for easy alignment in the field
• Robust sensor technology for reliable operation even under harsh conditions, protection classes IP 66 and IP 67
• Fast, state-of-the-art signal processor with powerful command set for efficient system

communication via serial or Ethernet interface
• Includes two trigger inputs for additional light barriers or optical switches for high precision edge detection and offset length compensation
• Hardware status signals for remote diagnostic functions available
• User-selectable full quadrature pulse output and interfacing as LAN & RS 422/232
