T echnology U pdate Mac NDT test systems

NONDESTRUCTIVE test instruments and Systems from Magnetic Analysis Corporation (MAC) were exhibited at the Polimeter Comércio e Representações Ltda booth at Tubotech, São Paulo in October. Polimeter is MAC’s representative for Brazil, Chile and Argentina. MAC uniquely offers three different test technologies, eddy current, ultrasonic, and flux leakage. MAC’s ability to provide a choice of technologies is a distinct advantage. By combining eddy current and ultrasonic technology, for example, superior test results can be obtained as each technique detects the conditions that it is best suited to find. Applications include inspecting welded and seamless tubes as well as Oil Country Tubular Goods (OCTG) with or without upset ends. Both ferromagnetic and non-ferromagnetic materials can be successfully tested.

Information on the MultiMac ® Eddy Current, Echomac ® FD-4 Ultrasonic, and Rotoflux ® flux leakage test instruments and systems was available at Tubotech. The versatile MultiMac with up to eight test channels can be used to detect transverse, non- continuous and/or longitudinal, seam- type surface defects. MultiMac operates with encircling/ sector test coils or rotary test probes, depending upon the specific application and type of defects that need to be detected. The Echomac FD-4 instrument features up to 32 independent test channels. It provides superior performance for flaw detection, and measurement of wall thickness, ID, OD, ovality and eccentricity. Echomac FD-4 can be used with MAC’s rotating transducer units as well as with new or existing immersion, squirter and

other couplant type installations. The Rotoflux tester is available for transverse and longitudinal flaw detection. With 48 channels, the Rotoflux systems meet demanding industry standards for heavy wall OCTG tube. A recent system for a tube mill has the capability of testing to within 1" from the tube end. A range of mechanical handling, test coil platforms, automated controls and reporting capabilities are also available from MAC. Magnetic Analysis Corp is a market leader in Brazil for eddy current tube test systems and all MAC equipment can be delivered with software and operating instruction manuals in Portuguese.
