Penetrant Testing (PT)
Aden ProGas offers Liquid Penetrant Testing (PT) to identify surface discontinuities in materials such as welds, pipes, and pressure vessels across construction projects and process plants. This method is widely used for its sensitivity and simplicity in detecting flaws on the surface.
Benefits of Penetrant Testing
Highly sensitive to detecting small surface discontinuities.
Effective for inspecting parts with complex shapes.
Suitable for large areas and volumes of materials, offering quick and affordable inspection.
Versatile, applicable to metallic, nonmetallic, magnetic, nonmagnetic, conductive, and non-conductive materials.
Flaws are visible directly on the part surface, providing a clear visual representation.
Portable, with aerosol spray cans making the process convenient and inexpensive.
Reveals relative size, shape, and depth of surface flaws.
Simple to use and requires minimal training.
Limitations of Penetrant Testing
Only detects defects that break the surface.
Limited to materials with nonporous surfaces.
Requires thorough pre-cleaning to avoid masking defects.
Metal smearing from machining or blasting must be removed prior to testing.
Inspector must have direct access to the inspected surface.
Surface finish and roughness can impact inspection sensitivity.
Involves multiple steps that need strict control.
Post-cleaning is necessary for acceptable parts.
Requires handling and proper disposal of chemicals used in the process.
