Liquid Penetrant Testing (PT)
Service Overview
Surface Inspection for Detecting Fine Discontinuities
Liquid Penetrant Testing is a surface examination method used to detect surface-breaking discontinuities in non-porous materials. A penetrant is applied to the prepared surface and, after the required process steps, indications become visible
for evaluation.
Typical Applications
Welded Joints
Inspection of weld surfaces for cracks, porosity and other surface-breaking discontinuities.
Piping & Components
Examination of non-porous piping, fittings and components for surfacebreaking discontinuities.
Machined & Fabricated Parts
Inspection of machined and fabricated surfaces where fine discontinuities may not be readily visible.
Inspection Objectives
Detect Surface Defects
Reveal cracks and other discontinuities that are open to the inspected surface
Improve Defect Visibility
Make fine surface indications clearly visible for inspection and evaluation.
Verify Surface Integrity
Assess inspected surfaces for relevant discontinuities affecting component quality and integrity.
