Magnetic Particle Inspection (MPI)<\/h1>\n
<\/div>\n

Surface and near-surface crack detection in ferromagnetic materials \u2014 dry and wet fluorescent methods.<\/p>\n <\/div>\n<\/div>\n\n\n\n

What is MPI?<\/span>

Magnetic Particle Inspection<\/h2>

MPI detects surface and near-surface discontinuities in ferromagnetic materials by magnetising the component and applying iron particles \u2014 defects cause particle accumulations visible under normal or UV light.<\/p>

Our procedures comply with ASME Section V, AWS D1.1, API 1104, and client-specific codes.<\/p><\/div>

How It Works<\/span>

Inspection Process<\/h2><\/div>
01<\/div>

Magnetise Component<\/h3>

Apply magnetic field using yoke, coil or prod technique as appropriate.<\/p><\/div>

02<\/div>

Apply Particles<\/h3>

Apply dry powder or wet fluorescent particles to the magnetised surface.<\/p><\/div>

03<\/div>

Inspect<\/h3>

Examine surface under white light or UV light for particle accumulations indicating defects.<\/p><\/div>

04<\/div>

Demagnetise<\/h3>

Remove residual magnetism after inspection is complete.<\/p><\/div>

05<\/div>

Report<\/h3>

Document all indications with location, size and accept\/reject status.<\/p><\/div><\/div><\/div><\/section>\n\n
