One small handful of rejected materials, identified during a run of 30,000 high-precision components, is one handful too many,” asserts John Pechan, Chief Operating Officer at Round Ground Metals® (RGM®).
Minimac® II, Magnetic Analysis Corp.’s latest eddy current tester, will be featured at Booth #607 at Wire Expo. This addition to MAC’s range of eddy current test instruments for detecting surface and sub-surface defects such as laps, slivers and cracks in non ferrous and ferrous wire and rod, features an embedded processor host computer, and can be supplied with one or two test channels.
The customer, a tube manufacturer in India, faced difficulties when it came to performing electromagnetic testing on larger tubes, with diameters ranging from 180 mm to 250 mm. Their previous testing system, which was based on eddy current testing (ECT) with an encircling coil, was effective for tubes with diameters up to 180 mm. However, the sensitivity of the system, which is inversely proportional to the tube diameter, significantly decreased when testing larger tubes. The customer needed a solution that would maintain the same level of defect detection sensitivity while accommodating the increased tube diameter. This posed a challenge for achieving the required test defect size, through drilled holes (TDH), consistency and defect sensitivity with heavier wall thicknesses.
Edson José Eufrásio and Matt Rutledge dive into the latest developments in Magnetic Flux Leakage (MFL) testing—covering new technologies, evolving standards, and emerging market needs in this discussion titled "A New Era of MFL". Edson José Eufrásio brings over 40 years of experience in NDT, inspection, and quality management across the steel and oil & gas sectors. A former Director of NDT Technology at Vallourec and President of ABENDI, Edson is now consulting for Magnetic Analysis Corporation. He is an ASNT Level III in ET, UT, and MT, with advanced degrees in mechanical and metallurgical engineering and business management. Matt Rutledge, Vice President of PITCO, LLC, has more than 16 years of experience in OCTG inspection and MFL technology.

Responding to the expanding supply of natural gas and oil which has spurred a need for larger diameter tube and pipe, Magnetic Analysis Corp. (MAC) has supplied its largest ever model Ultrasonic Rotary tester to a major Russian pipe producer. Part of MAC’s line of Echomac® nondestructive Ultrasonic testers, this model can inspect tube and pipe up to 500mm (19.6”) diameter.

Precision tubes for the automotive industry must meet the highest performance requirements. MAC’s® Eddy Current, Flux Leakage and Ultrasonic systems are often used to inspect tubes destined to be cut into short lengths to be fabricated into a critical automotive component.
Eddy Current technology is the go-to wire and cable testing method for checking continuity, alloy, surface flaws and other conditions as well as for locating welds and splices. MAC® instruments can handle a range of metal wire including cut lengths, continuous production, stranded, multi-conductor and insulated cable.
There are many welding processes and many tubing configurations and sizes. MAC has extensive experience testing tubes and pipes using eddy current, ultrasonic, and flux leakage technologies. We have a large base of testing equipment lines being used to meet the many different ASTM, API, EN, ISO and other industry quality standards and or customer driven quality requirements.
