CRC CRICK 130

Developer for non-destructive testing

Ref. : 10879

1. GENERAL DESCRIPTION

A quick drying developer, for the non-destructive testing of surfaces and structures. Many

cracks in engineering materials can be deep in spite of having a very small opening width on

the surface and can cause very serious defects. By normal visual inspection such cracks

may be very difficult to detect, but penetrant flaw detection is an extension of the visual

inspection method. The control is carried out using 3 products: Crick 110 (cleaner), Crick 120

(penetrant) and Crick 130 (developer). Crick 130 is a dispersion of a white powder in a fast

evaporating solvent.

2. FEATURES

• The check can be carried out with ready-to-use aerosols.

• It produces results in a speedy and easy way.

• An economical technology with no need for expensive and advanced equipment.

• A sensitive and reliable test method.

• Widely applicable, regardless the nature of the materials and shape of the objects.

• The aerosol uses a hydrocarbon propellant for controlled application.

• Approvals : ASME Section V, Art 6.

3. APPLICATIONS

Non-destructive inspection of materials, parts, assemblies, equipment, surfaces or

structures:

• Cracks, lack of fusion and open cavities in welded parts.

• Cracks and cavities caused by metal fatigue and cutting operations.

• Check of porosity or leaks in pipes, tanks, boilers, heat exchangers.

• Discontinuities, laps, folds and cracks in castings, forgings and ceramics.

4. DIRECTIONS

Do not use at ambient temperatures below 10'C.

• In liquid penetrant inspections, the test object or material is coated with a visible dye

solution. The excess dye is removed from the surface and a developer is then applied. The

developer acts like a blotter and draws penetrant out of the imperfections of the surface.

With visible dyes, the vivid color contrast between the penetrant and the developer makes

the ‘bleed-out’ easy to see.

• Cleaning of the surface

The surface to be checked must be clean, degreased and dry. All soil, like rust, oil, grease,

paint etc, which can mask the imperfections, must be removed. Finish the cleaning by

spraying Crick 110 generously. If possible wipe with an absorbent cloth and allow drying

thoroughly.

Spray the penetrant in a light, even film on the surface, wetting all areas to be controlled. Allow to drain for 10 to 20 minutes. • Excess penetrant removal Remove excess of penetrant by wiping the surface using a lint-free cloth. Apply water (Crick 120 is water washable) until all visible, coloured traces are removed.
