S-MPI-PufferSilicone Magnetic Particle Inspection- DRY Powder Puffer Helpful Hint: Dry magnetic powder inspection is particularly suited to inspections on rough surfaces such as un -ground welds and rough castings. In addition to surface-breaking flaws, dry powders can also be used to detect sub-surface faults. With dry method testing, no carrier fluid is involved, so dry powders can be used for testing hot surfaces. However, the absence of a carrier fluid means that they will lose mobility once the particles are on the surface. When using dry powders, it is important to ensure that the surface is dried thoroughly after cleaning. Dry powders are treated as disposable and should not be re-used on account of the risk of contamination from dirt and moisture. Show more
