Six Advantages of the MagnaFORM Probe Over Penetrant Testing in Stainless Steel
Using penetrant testing to inspect stainless steel pipes for stress corrosion cracking and welds for cracks can be a slow job. Many pipes are rough, dirty, or painted. Before penetrant testing can be used, the pipes must be smoothed and cleaned. If they’re painted, it must be painstakingly stripped off and the pipe later repainted. Luckily, there’s a better way.

Here are 6 advantages of the MagnaFORM™ eddy current array (ECA) probe over penetrant testing.

1. No more paint removal and repainting
The MagnaFORM probe works with the OmniScan® MXE flaw detector to deliver reliable imaging through paint—no stripping or repainting required. This enables you to get the job done faster.

2. Rough surfaces won’t slow you down
Dynamic lift-off compensation helps ensure that the probe remains sensitive to surface-breaking defects on rough welds and corroded areas. Even with up to 3 mm of lift-off, the detection remains reliable.

3. Dirty parts are no problem
If the component you’re inspecting is dirty, wet, rough, or cold worked, the solution’s signal-to-noise ratio remains high, helping you spot defects quickly.

4. One setup for 304 and 316 stainless steel
With one predefined setup, you can inspect both 304 and 316 stainless steel. Defects as small as 1.6 mm long can be detected.

5. More coverage = faster inspections
The MagnaFORM scanner can cover up to 65 mm (2.56 inches) each scan, helping you get the job done fast.

6. Won’t wear you down
The probe has replaceable wedges and built-in wear protection that will last you for an estimated 22 kilometers (13.7 miles) of inspection.

The MagnaFORM solution includes the probe, scanner buggy, and 5-meter cable. The lift-off compensation software is loaded on a flash card and is used with the OmniScan MXE flaw detector.
