Dye Penetrant Testing

Dye Penetrant Inspection (LPI) for used extensively for detecting discontinuities open to surface such as cracks, seams, laps, cold shuts, laminations, though leaks, nonporous, non-metallic materials, both ferrous and non-ferrous. Liquid penetrant is also known as Dye penetrant inspection uses Dye penetrants that is applied to surfaces and allowed to seep into surface opened discontinuities.
After removal of excess penetrant the surface is then applied with developer that brings back the penetrant on to the surface due to blotting action of the developer. For better visibility and contrast with developer, penetrants are added with red color or fluorescent dyes. Penetrants are classified based on the sensitivity and method of excess penetrant removal.


Penetrant materials Classification Based on Standards

As per ASTM E165 penetrants are classified as

  • Type 1 (Fluorescent)
  • Type 2 (Visible Red)
Based on the method of Penetrant Removal Process classified as
  • Method A (Water Washable)
  • Method B (Post Emulsifiable – Lipophilic)
  • Method C (Solvent Removable)
  • Method D (Post Emulsifiable – Hydrophilic)
Based on Penetrant Sensitivity Classified as
Level 1/2 – Ultralow
Level 1 – Low
Level 2 – Medium
Level 3 – High
Level 4 – Ultrahigh

In general, Sensitivity and type of penetrant is selected based on applicable specifications, product codes and application of the components.


Penetrant testing Equipment Sales

Portable Penetrant testing kits are good for field or site NDT testing. And, for mass production and better sensitivity stationery type PT systems will do better. Trinity NDT supplies Fluorescent Dye Penetrant Inspection System as per the demands of Aerospace companies and other automotive Industries. The DPT system is supported by facilities which make the Testing Reliable and Repeatable. Post emulsifibale and water washable test systems and lines are of much use in aerospace NDT environment.

DPT testing Accessories Sales

Penetrant testing needs other accessories to perform the test, validate the results and satisfy the demands of standards. Below accessories are of major use in PT testing. Trinity NDT – Sales division supplies the following accessories at Bangalore in India. We also supply for Hosur, Mysore, Mangalore, Shivamogga, Bellary and Belgaum. Contact us for price, stock availability and delivery schedules.

Ultraviolet Light(UV), Black light Intensity Meter

UV Black light Intensity Meter for NDT testing
UV Black light Intensity Meter for NDT testing

UV Light intensity meter or Radiometer is used for measuring Ultraviolet UV light or Back light intensity. UV light meters needs calibation (usually once on six months) as per testing procedure or standard. The instrument will be useful for measuring (Checking) intensity of UV/ Black Light Bulbs in Liquid Dye Penetrant testing. The UV light meter comes with a sensor for checking. Quality of instrument and sensor is vital. We supply UV light meters from our sales division in Peenya Bangalore.

Lux Meter for Measuring Visible Light Intensity

For Checking intensity of White Light lux meter is required. Lux meter measure visible light intensity at wavelengths 400nm to 700nm. All light intensity meter such as lux meter is to be calibrated once in 6 months as per ASTM E165. Lux meter comes with sensor for visible light intensity checking.

UV Goggles for UV Light Protection

UV or black light emits a range of ultra voilet spectrum from the light. But, the wave lenght from 320nm to 400nm is complete safe and this the UV goggles can help to filter the harmful wavelengths emitted from UV Black light used in NDT testing. Protection to eyes against UV radiations while inspecting is possible using UV goggles.

Aluminium Comparator Block for DPT testing

Aluminium comparator blocks are useful for Testing Sensitivity of the Penetrant and for comparison between different Penetrants. Thes comparator block have multiple cracks that are produces for verification of sensitivity. One the quite useful calibration block used in general penetrant testing other than aerospace NDT applications. Run the panel for each penetrant new batch and verify the quality of penetrants.
