Uses

·          It can be used for nonferrous materials like porcelain, glass synthetic resin as well as metal, iron. Nonferrous metal, magnetic substance and nonmagnetic substance.

·          Casting parts --- pin hole, scalding flaw, shrinkage flaw forging parts --- forging flaw.

·          Weld --- crack, failed joining.

·          Metal materials --- grinding flaw, heat flaw, cutting fool crack.

·          Leakage check --- tank, boiler, pipe etc.

How to use

·          Coloring Penetration Detection Method disovers invisible flaws easily by making red penetrant liquid penetrate into surface flaw areas of inspection object, removing residual red penetran liquid with cleaner, and developing red penetrant in flaw areas by using white developer and capillary phenomenon.

·          Everyone can use the detection method by following operations.

1.        Pre-trement

The dirt like dust, oil content, coating materials and rust prevents penetration of red penetrant. Remove them completely with cleaner before inspection.

Be careful of pre-treatment method to prevent surface flaw areas from being clogged.

The more perfect the pre-treatment is, the higher the detection effects are and easier the inspection operations.

2.        Penetration

Clean the inspection object surface and dry it.

Apply red penetrant evenly 2-3 minutes. Application at the intervals of 3-6 minutes ensures better effects.

Recommended temperature of parts for inspection is about 10-40°C.

When you do this inspection work outdoors in winter, it is recommended that you should lengthen penetration by about two times to obtain better penetration effects.

(Also, as soluble penetrant is available, water rinsing is possible and onsite use is very easy.)

3.        Cleaning

After penetration treatment is done, remove red penetrant remained on the inspection object by using dry dust cloth, tissue paper, other absorbents or water rinsing (in case of soluble penetrant) and clean the object with dust cloth containing cleaner or tissue papers.

If weld with surface not smoothed or inspection object with black flim of steel and casting products are not cleaned completely and red penetrant is remained on their surface, it is difficult to determine flaw correctly in developing.

Use white or near-white dust cloth or tissue paper to know cleaning degree easily.

Do not apply it directly to the surface of inspection object.

4.        Development

After cleaning red penetrant remained after penetration, apply white developer evenly to make it cover whole surface.

Applied white developer is dried immediately, showing white color.

As it dries, red penetrant in flaw areas is absorbed and appeared making the position and shape of flaw marked sharply on the white powder phase.

Shake white developer light before use.

5.        Inspection

The areas not showing red after development means that they have no flaws.

Determine the kinds, size and depth of red stained areas on the basis of their shape and size.

The kinds of flaw created by color fixation can not be determined by single word but can show them as following.
