What Liquid Penetrant Testing (PT) actually detects

Penetrant testing draws a low-viscosity dye into surface-breaking discontinuities by capillary action, then reveals it with a developer. It works on non-ferrous and non-magnetic materials where magnetic particle testing cannot be used.

Surface-breaking cracks in stainless steel, aluminium and titanium
Porosity open to the surface
Laps, seams and cold shuts in castings and forgings
Fatigue cracking in aerospace components
Leak paths in thin-wall welded joints

Codes and acceptance criteria applied

Examinations are performed to written procedures qualified against ASME Section V Article 6, ASME Section VIII Division 1 Appendix 8, ASTM E1417, AWS D1.1 and ISO 3452. Acceptance criteria are taken from the construction or in-service code governing the item — ASME Section VIII for pressure vessels, ASME B31.3 for process piping, API 510, API 570 and API 653 for in-service equipment, and AWS D1.1 for structural steel.

How the examination is controlled in Tampa

Agree personnel qualification, equipment checks, procedure revision and review responsibilities for the examination. Retain those records with the results and coverage limitations.

Reporting and follow-up

Results are issued in the client's required format with indications located against the component and, where relevant, against a corrosion monitoring location so thickness trends stay continuous between campaigns. Findings can be delivered into the client's own maintenance system, or onto a 3D asset model where remaining life and risk-based inspection ranking update as new data arrives.

Prepare a useful penetrant examination scope

Confirm a suitable nonporous surface and an examination objective involving surface-breaking discontinuities. Provide the material, surface finish, temperature conditions and any restrictions on inspection materials or cleaning products.

Understand the technique limitations

The approved technique governs preparation, penetrant application, removal, development and examination conditions. Contamination, smeared surfaces or unsuitable preparation can obstruct openings. Penetrant inspection cannot establish the condition of discontinuities that do not open to the examined surface.

Specify the records and review

Keep part identity, examination area, material system, procedure revision and indication locations in the report. Separate the observation of an indication from its evaluation against the specified acceptance criteria. Agree post-examination cleaning and handling with the owner.
