Liquid Penetrant Testing (LPT)

Liquid penetrant testing (LPT) is a method of non-destructive testing using colour contrast and fluorescent penetrant for detecting surface discontinuities which are open to the surface.

LPT can be used for non-porous materials on welds or materials of any shape or size.

SST-NDT provides testing services in liquid penetrant testing including fluorescent and visible solvent. Working to applicable codes and specifications, SST-NDT can apply LPT on:

  • Offshore platforms
  • Construction and maintenance of pipelines
  • Pressure vessels
  • Bridges
  • Cranes, tanks and tankers
  • Aerospace vehicles
  • Power generation equipment
  • Research facilities
