Liquid Penetrant Testing (LPT)

LPI is widely applied as low cost inspection method used to locate surface breaking defects in all non-ferrous materials and ferrous materials; although for ferrous components magnetic particle inspection is often used. LPI is used to detect casting, forging & welding surface defects such as hairline cracks, surface porosity, leaks in new products and fatigue cracks on in-service components. We offer on-site liquid penetrant testing services using contrast or fluorescent penetrant for highly sensitive inspection. We offer on-site liquid penetrant inspection services. For detecting of surface breaking cracks in non-magnetic materials, we use both color contrast and fluorescent penetrant for highly sensitive inspection.

APPLICATIONS:

• It is used to inspect metals for surface defects
• Weld discontinuities open to surface i.e. cracks, porosity and seams

ADVANTAGES:

• It can be used on a wide variety of materials: ferrous and nonferrous metals and alloys, fired ceramics, powdered-metal products, glass, and some types of organic materials
• Portable, relatively inexpensive equipment
• Expedient inspection results
• Results are easily interpreted
• Requires no electrical energy except for light source
• Indications may be further examined visually
• Adapted to volume processing permitted 100 percent surface inspection
