NDT test systems on display at Tube India

DFT

NDT TEST instruments and systems for inspecting tube, pipe and bar will be featured at Magnetic Analysis Corp (MAC) and Inmar Engineering Corp’s booth B30 in Hall 2 at Tube India 2024 in Mumbai. Highlights of the booth will include a demonstration of the new Minimac ® II eddy current tester inspecting small diameter tube, and information on MAC’s latest “spin the tube” ultrasonic system for testing seamless carbon steel tubes in an Indian tube mill. With an embedded host computer, the Minimac ® II is a fully digital instrument that can operate any combination of one or two flaw or absolute test channels and Magnetic Inclusion Detector (MID), with high reliability and performance, at an economical cost. Operating at speeds up to 4,000fpm this instrument can detect short surface and some subsurface defects, including laps, slivers and cracks in tube, bar and wire. Minimac ® II can be used to find weld-line faults in tube, check continuity in single and multi-conductor insulated wire and cable and test flux core wire to detect missing flux as well as flaws in the wire. Minimac ® II, housed in a rugged, fanless design, can operate with encircling test coils or rotary probe systems. MAC’s business development manager in India, Parag Nag, and other booth personnel, will be available to discuss the “spin the tube” ultrasonic test system designed to inspect seamless carbon steel tubes ranging from 219.1mm to 500mm diameter, at a mill in India. The system features Echomac ® FD-6 multi channel electronics, paired with a comprehensive conveyor system that rotates and advances the tubes in a helical pattern past the test heads that are raised from beneath. The test heads incorporate a unique Automatic Pitch Control (APC) design that adapts the angle of the surface ride rolls for each tube diameter size to ensure a constant pitch is maintained. The actual transducer holder within the test head can move to either end of the water box to minimise untested ends. The full system is controlled by a PLC integrated with the Conductor system for operator interface communication via a touch screen and other applicable plant systems for information exchange. The Echomac ® tester, using 60 channels of electronics, will be detecting longitudinal defects in the CW and CCW directions and transverse defects in the forward and reverse directions, as well as lamination defects and wall thickness measurements.
