Complete Magnetic Particle Inspection

THE POWER OF COMBINATION
Discover how the combination of Supermagna Yoke HMM6 , magnetic powder particles , BC 502 SN Conditioner and 104C Contrast ensures fast, compliant and safe magnetic particle inspections .

In industrial maintenance, the reliability of inspections is crucial to avoid rework, equipment failures, and costs associated with unscheduled downtime.

Among Non-Destructive Testing (END) methods, magnetic particle inspection (MPI) is one of the most widespread techniques for detecting surface and subsurface discontinuities in ferromagnetic materials .

For reliable results, good magnetization equipment alone is not enough. High-quality magnetic particles, a suitable conditioner, and an effective contrast agent are also necessary .

This is where Metal-Chek stands out, offering a robust combination for the industry: the Supermagna Yoke HMM6 , magnetic powder particles associated with the BC 502SN Conditioner and the 104C Contrast .

Supermagna Yoke HMM6: Robustness and Compliance

The Supermagna Yoke HMM6 is an electromagnetic yoke designed to generate the necessary magnetic field during inspection.

Main features:

Portable and robust – ideal for field and factory inspections.
Safe – it does not conduct current through the part, but induces a longitudinal magnetic field.
Versatile – suitable for inspecting welds, castings, forgings, metal structures, etc.

Regulatory – complies with the main national and international standards.

Magnetic Particles + BC 502 SN Conditioner

The use of magnetic powder particles , combined with BC 502 SN Conditioner , is the most widely adopted method for forming stable and efficient suspensions.

Function of magnetic particles:

They make surface and subsurface discontinuities visible by accumulating in regions where the applied magnetic field escapes.
The concentration can be adjusted according to the procedure.
Available in different options for visible or fluorescent inspections.

Function of BC 502 SN Conditioner:

It guarantees corrosion protection .
Allows for uniform dispersion of particles .
It promotes proper moisturization and mobility on the surface.
Compliant with technical standards requirements.

104C Contrast: Enhanced Visibility and Precision

Contrast 104C is applied before magnetization and magnetic particle bathing, creating a uniform white background .

Main functions:

It increases the contrast between the particles and the surface.
Increased sensitivity of the assay.
Compliance with technical standards.

How the Combination Works

Applying Contrast 104C – creates a contrasting and uniform white background.
Magnetization with the Supermagna Yoke HMM6 – generates the necessary magnetic field.
Application of the prepared suspension (particles + BC 502 SN) – the particles agglomerate in the leakage field regions, forming indications.
Interpretation – with a white background and highlighted particles, the inspector can quickly and reliably identify discontinuities.

Advantages of the Combination

High sensitivity in detecting discontinuities.
Operational speed , with results visible immediately.
Regulatory reliability , in accordance with ASTM, ISO, AMS, ASME and PETROBRAS standards.
Flexibility , allowing adjustments to particle concentration.
Safety is ensured through the use of a robust and secure yoke in various environments.

Technical Standards Supporting the Set

The combination meets the requirements of international and national standards, such as:

ASTM E709
ASTM E3024
ISO 9934 (1 and 2)
NM 342
ASME BPVC Section V, Article 7
PETROBRAS N-1598

Magnetic particle inspection is an essential technique for industrial maintenance and quality assurance . However, its efficiency depends on choosing the right equipment and supplies .

The combination of the Supermagna Yoke HMM6 , magnetic particles with BC 502 SN Conditioner , and 104C Contrast ensures a fast, reliable, and safe inspection process.

With this complete solution, Metal-Chek reinforces its commitment to providing cutting-edge technology for Non-Destructive Testing , meeting the needs of the industry with excellence.
