Liquid Penetrant Inspection / Magnetic Particle Inspection

Liquid Penetrant Testing (PT) Inspection Services

Dye penetrant inspection (DP), also called liquid penetrant inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to check surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability. LPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.

Solvent Removal Method

Solvent removable visible red dye penetrant locates surface-breaking discontinuities with a simple three-step process that is ideal for basic industrial nondestructive testing. SKL-SP2 features high-performance penetrating characteristics and produces clear vivid red indications.

Fluorescent Penetrant Inspection

Fluorescent penetrant inspection (FPI) is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part in question. FPI is noted for its low cost and simple process, and is used widely in a variety of industries.

Magnetic Particle (MT) Inspection Services

Inspec Testing performs Dry Powder, and Wet Fluorescent Magnetic Particle Inspections.

Dry Method

Dry particles are dusted onto the surface of the test subject as the part is magnetized. The clustering of the magnetic particles is efficient for detecting defects on rough surfaces, including shallow and subsurface cracks. Dry methods are ideal for field inspections.

Wet Fluorescent Magnetic Particle (MT) Inspection

Wet Fluorescent Magnetic Particle Inspection is a more precise inspection than the dry particle method. This method is typically used for shafts, machine parts, bearings, castings, and crane hooks. Visibility of the indications is greatly improved because the eye is drawn to the glowing region of the dark setting. Inspec Testing offers Wet Fluorescent Inspections in shop or we can set up a containment and perform the inspection on the field.
