Water washable visible red dye penetrant, designed for:

  • General metalworking
  • Welding
  • Nuclear inspection applications

VP-30 is a visible (Type 2), water washable (Method A) and solvent removable (Method C) inspection penetrant. It is designed for use in general metalworking, welding, nuclear and automotive applications for surface flaw and through leak detection.

VP-30 has found wide use in the inspection of food and dairy processing equipment such as heat exchanges. Visible penetrants are not rated by sensitivity levels per AMS-2644 but are considered approximate to level 1 fluorescent penetrants. 50µ discontinuities are readily detected and under controlled conditions 30µ size defects may be high lighted by visible penetrants.

ISO-3452-2005 does rate visible penetrants by sensitivity level with #2 being the most sensitive. VP-30 is a level 2 per this specifications requirements.

VP-30 is listed on the Qualified Products List for AMS-2644E. It meets the requirements of ASME Boiler and Pressure Vessel Code, ASTM E-165, ASTM E-1417, and ISO- 3452-2005 for penetrant inspection materials. It is low in Sulfur, Chlorine, Fluorine and other Halogens, making it safe for use on Titanium and high Nickel alloys found in aerospace, medical and nuclear components.
