Marking pens

Low-halogen and sulfur type
Minimized impurities such as chlorine, fluorine, and sulfur marking pen .Used for marking on the surfaces of stainless steels and nickel-titanium alloys. Available 4 colors : black, red, white and blue .
Low-halogen and Low-sulfur type Marking pens
  • Special marking pen for nuclear power equipment and related parts.

Marking Ink (black) MB-5
Marking Ink (black) MB-5 was mainly developed for the copper pipes to be tested by eddy current testing. And this Ink is the fast drying type not to break out any detach even after annealing.

Test Panel

Test Panels are ideal penetrant sensitivity comparators. Having matched pairs enables studies of the effects of process changes as compared to a standard process, or used material changes vs fresh material. Test panels allow “in use penetrants to be compared against “new, unused” product to determine if the penetrant is performing properly.

How to use Test Panels

  1. Test Panels are used for penetrant-effectiveness testingandjudgmentoftesting process.
  2. ASME Type is used in principle as a pair of test panels separatedto twoportions bytheslit (center line). And the test panel also can be used by cutting-off to twopanels.
  3. Regarding to the penetrant-effectiveness testing, two kinds of penetrant materials to be compared shall be respectively applied to the pair of test panels separated by the center slit. And tested underthesameconditionforthe comparisonofthe effectiveness.
  4. For the judgment of testing process, the same penetrantmaterial shall be applied to the two test panels, and tested respectively by the different processfor thecomparisonof the testingprocess.
  5. One test panel should be used in common for testing of dye penetrant suspension and testing of fluorescent penetrant suspension.
