Ultrasonic and eddy current inspection for tubes

required to the basic water tank on size changeover. The spinning tube transducer system can also be installed as a retrofit or upgrade to existing installations. MAC will also be exhibiting the latest MultiMac ® eddy current testers and rotaries to detect surface, subsurface, ID and OD defects in tube and pipe, and 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. Both the ultrasonic and flux leakage systems are capable of testing to 5 per cent defect levels on the OD and ID of tubular products. Because MAC offers 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. The testers can easily be combined into complete, automated test systems including triple pinch benches to maintain accurate positioning, standard and custom conveyors, markers, sorters, demagnetisers, 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, and heat exchanger and Duplex tube. MAC’s knowledgeable field staff will provide information in multiple languages on all of the company’s products. See Magnetic Analysis at stand 6G40 in Hall 6.

WITH over 85 years of experience in designing and manufacturing non- destructive test instruments and systems for the metals industry, Magnetic Analysis Corp (MAC) will be featuring its newest ultrasonic, eddy current, and flux leakage inspection systems for tube manufacturers. Building on the success of MAC’s Echomac ® rotary ultrasonic testers, the company will be featuring a new spinning tube ultrasonic test system at Tube 2014. The system features an APC (automatic pitch control) transducer carrier that 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. 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
