As market pressures compel tube and pipe manufacturers to search for ways to increase productivity while maintaining adherence to strict quality standards, choosing the optimal inspection method and support system are more critical than ever.

Since the development of eddy current testing in the early to mid-1900s this method has been used to detect defects and properties of many types of metals. The most common applications are testing tubular products for transverse defects, testing bar or wire products for longitudinal surface defects, and testing parts for defects and properties such as hardness.

Magnetic Analysis Corporation (MAC®), a designer and producer of nondestructive test instruments and systems since 1928, is pleased to announce the asset acquisition of TacTic™, a Division of Laboratory Testing Inc. (LTI), effective February 28, 2022. Originally founded as TAC Technical Instrument Corp.

Magnetic Analysis Corp. (MAC) is a company established over 90 years ago providing non-destructive testing (NDT) equipment for the metals industry, primarily producers of tube, pipe, bar, wire, and parts. The company’s focus is in-line automated testing systems ensuring the identification of defects that would impair the functionality of the product.

Increasing demands for high-quality steel rod and bar requires effective nondestructive (NDT) testing to ensure producers can meet their customer’s needs. As specifications become ever more stringent, NDT technology is consistently evolving new capabilities, adapting to new conditions and improving integration with mill operations.

Industrial heat exchanger users, aerospace, medical, and some military applications require the highest quality materials and also demand high inspection levels for long intermediate products (wire, tube, and bars). Surprisingly, automotive materials can also require the highest quality because defects in safety-critical components or parts integral to engine lifetime or fuel systems can lead to huge expenses.

Eddy Current inspection is a technique used for detecting surface seams, cracks, pits, slivers, and internal discontinuities in ferrous and non-ferrous wire. Different test sensor configurations, including encircling coil and rotary probes, can be used. When using encircling coil eddy current testing, the wire passes through the coil excited by an alternating current with one or more drive signals.

Magnetic Analysis Corp., a global leader in instruments and systems for the nondestructive testing of metals, is pleased to announce the appointment of Daniel Lawrence as President and Chief Executive Officer effective November 6th, 2023.

Magnetic Analysis Corp. will feature the Minimac® II at its booth. This latest addition to MAC’s range of eddy current test instruments for detecting surface and sub-surface defects such as laps, slivers and cracks in nonferrous and ferrous wire and rod, features an embedded processor host computer, and can be supplied with one or two test channels.

Magnetic Analysis Corp. will be featuring the “Minimac II” at its booth which is to find in the tube section. Wire producers are invited to come over to see products that are applicable to both wire and tube.
