Magnetic Analysis Corporation (MAC®) is a global NDT systems and equipment manufacturer specializing in automated and semiautomated nondestructive testing solutions for tube, pipe, bar, wire, and other metal products. MAC designs and manufactures ultrasonic testing (UT), eddy current testing (ET), phased array ultrasonic testing (PAUT), and magnetic flux leakage (MFL) inspection equipment for manufacturers that require reliable, high-speed, nondestructive inspection.
With nearly a century of experience in nondestructive testing, MAC combines inspection electronics, sensors, probes, transducers, mechanical systems, software, and material handling mechanisms to create complete NDT inspection systems tailored to individual production requirements.
What Is NDT Equipment?
Nondestructive testing (NDT) equipment is used to inspect materials and components for defects without damaging or destroying the product. NDT methods allow manufacturers to identify discontinuities, measure material characteristics, and verify product quality during or after production.
Common industrial NDT technologies include:
- Ultrasonic Testing (UT)
- Eddy Current Testing (ET)
- Phased Array Ultrasonic Testing (PAUT)
- Magnetic Flux Leakage (MFL)
The right NDT technology depends on the material, product geometry, defect type, required inspection coverage, and production speed.
Ultrasonic Testing (UT) Equipment
Ultrasonic testing (UT) uses high-frequency sound waves to detect internal, surface, and subsurface discontinuities.
MAC's Echomac® ultrasonic testing systems include UT rotaries, ultrasonic electronics, transducers, and complete inspection solutions for tube, pipe, bar, and specialty applications.
UT systems can be configured for:
- Tube and pipe inspection
- Seamless tube inspection
- Welded tube inspection
- Round bar inspection
- Wall thickness measurement
- Internal flaw detection
- Surface and subsurface flaw detection
- Dimensional measurement
- Semiautomated production-line inspection
MAC's Echomac® UT rotaries use multiple ultrasonic transducers to inspect round products at production speeds. Different rotary configurations are available for applications ranging from small-diameter tubing to larger diameter tube/pipe product.
Eddy Current Testing (ET) Equipment
Eddy current testing (ECT) uses electromagnetic induction to inspect materials for surface and near-surface defects.
MAC's MultiMac® and Minimac® eddy current testing systems can be integrated with encircling coils, bobbin coils, rotary probes, and other inspection configurations.
Eddy current testing is commonly used for:
- Wire inspection
- Small diameter tube inspection
- Bar inspection
- Weld inspection
- Surface defect detection
- Crack detection
- Seam detection
- Corrosion detection
- Comparator inspection
- High-speed production inspection
Encircling coil eddy current testing is particularly effective for high-speed inspection of continuous products such as wire and bar. Rotary eddy current systems focus on transverse defect inspections.
Phased Array Ultrasonic Testing (PAUT)
Phased array ultrasonic testing (PAUT) is an advanced form of ultrasonic inspection that uses multiple transducer elements controlled electronically to steer and focus ultrasonic beams.
PAUT provides greater flexibility than conventional single-element ultrasonic testing because the ultrasonic beam can be electronically manipulated without mechanically moving the transducer.
MAC's Echomac® PA phased array systems can be configured for automated inspection applications where manufacturers require high sensitivity, coverage, and data acquisition.
PAUT can be used for applications including:
- Tube and pipe inspection
- Weld inspection
- Critical component inspection
- Crack detection
- Internal flaw detection
- Complex inspection geometries
Magnetic Flux Leakage (MFL) Equipment
Magnetic flux leakage (MFL) is an electromagnetic nondestructive testing method used to identify discontinuities in ferromagnetic materials.
During MFL inspection, the material is magnetized. Defects or changes in the material can cause magnetic flux to leak from the surface, where sensors detect the resulting signal.
MAC's MacFlux® DC magnetic flux leakage systems provide automated MFL inspection for applications including OCTG, oil and gas pipe, casing, tubing, and other ferromagnetic products.
MFL can be used to detect:
- Pitting
- Corrosion
- Metal loss
- Cracks and discontinuities
- Surface and subsurface defects
Complete NDT Inspection Systems
For many manufacturers, individual NDT instruments are only one part of the solution. A complete NDT system may combine multiple inspection technologies with mechanical handling, controls, software, marking, sorting, and data collection.
MAC specializes in integrating UT, ET, PAUT, and MFL technologies into production-line inspection systems.
For example, MAC's OCTGComplete® combines multiple inspection technologies into a single-pass inspection concept for OCTG applications, helping manufacturers reduce the need for separate inspection lines while increasing automation and production efficiency.
Why Choose MAC® as an NDT Equipment Manufacturer?
Choosing an NDT equipment manufacturer is about more than selecting an instrument. Manufacturers need technology that can integrate into their production process and consistently meet inspection requirements.
MAC provides:
- Automated and semiautomated NDT inspection systems
- Ultrasonic testing equipment and systems
- Eddy current testing equipment and systems
- Phased array ultrasonic equipment and systems
- Magnetic flux leakage, AC and DC, inspection equipment and systems
- NDT electronics and instrumentation
- Rotary inspection systems
- Encircling coil systems
- Inspection software and controls
- Material handling integration
- Custom-engineered inspection solutions
- Installation, training, calibration, and service
- Lease or own terms for systems and equipment
MAC's approach combines NDT technology and expert engineering to create complete inspection solutions rather than simply supplying individual test instruments.
One NDT Manufacturer. Multiple Inspection Technologies.
Different products and applications require different inspection methods. In many cases, combining technologies provides more comprehensive inspection coverage.
UT can provide volumetric inspection and thickness measurement.
ET provides highly sensitive detection of surface and near-surface defects in materials.
PAUT provides electronically controlled ultrasonic beams for advanced inspection applications.
MFL provides magnetic inspection for detecting discontinuities in ferromagnetic products.
By combining these technologies, MAC can help manufacturers develop an NDT inspection system designed around their specific product, production speed, defect requirements, and quality standards.
