Visible Dye Penetrant
 

VP-31A - Solvent removable and post emulsifiable, low viscosity, purple colored. (Type II, Method B or C).

 - Use either Met-L-Chek E-59 or E-59A cleaner/remover (method C)

 - Use Met-L-Chek E-50 emulsifier is used to render the penetrant film water (method B)

 - Met-L-Chek D-70 non aqueous developer is used to form a uniform background to facilitate discontinuity detection.

 VP-31A is qualified to AMS-2644 . They meet the requirements of ASME Boiler and Pressure Vessel Code, ASTM E-165, and ASTM E-1417 for penetrant inspection. They are low in Sulfur, Chlorine, and other Halogens, making them safe for use on Titanium and high Nickel alloys in nuclear applications. They are certified to NAVSEA 250-1500-1, RDT,and EdF; RCC-M.Visible inspection penetrants are used primarily for field applications were darkening the inspection area and the use of a black light (UVA) is impractical, in maintenance repair and safety checks, and in manufacturing processes where a visible indication helps in locating the area for subsequent repair work, such as in large rough castings. Visible penetrants are also used for through leak testing of heat exchangers and tanks, where penetrant is applied to one side and developer to the other.As a general rule of thumb visible penetrant inspection is roughly equal to level 1 sensitivity fluorescent penetrant inspection. Discontinuities in the range of 50µ are routinely detectable and under the right conditions and processing 30µ discontinuities can be highlighted.
