Magnetic particle Inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The method is used to inspect a variety of product forms including castings, forgings, and weldments. Many different industries use magnetic particle inspection for determining a component’s fitness-for-use. Some examples of industries that use magnetic particle inspection are the structural steel, automotive, petrochemical, power generation, and aerospace industries. Magnetic particle testing detects weak spots and damaged sections of metal without harming or staining the object, allowing you to perform repairs more effectively. Our technicians serve Fort St. John and Western Canada area, and are extremely skilled at catching even the smallest fractures, so you can rest easy.
When your employees’ safety or your company work flow depends on your physical structures, you can’t afford to have a little leak or ignore a problem. 20/20 NDT Inc. provides quick, on-site evaluations and excellent communication and reports, so you can stop emergency repairs before they happen.
How Magnetic Particle Testing Works
A liquid or powder solution composed of fluorescent and ferrous materials is sprayed on the magnetized section of pipe. The ferrous materials will be attracted into the cracks, and the fluorescence will show these cracks plainly under ultraviolet light.
The Benefits of Magnetic Particle Testing
Cracked and damaged pipes can have far-reaching consequences, not to mention liability concerns. Testing for damage can benefit your company in many ways:
- Magnetic particle testing is a relatively fast process.
- You will see immediate results, indications are visible directly on the surface.
- Indications can show relative size and shape of the discontinuity.
- Low-cost compared to some other NDE methods.
- This type of testing works in areas small or large.
- Post-cleaning generally not necessary.
- Can detect both surface and near-surface indications before they become major issues.
- A relatively safe technique; materials generally not combustible or hazardous.
- A portable NDE method, especially when used with battery-powered yoke equipment.
