Safety management and characteristics of penetration test

    Safety management

    The flaw detection agents used in penetrant testing are almost all oily flammable substances. Special attention should be paid to fire prevention. The flaw detection agents are generally non-toxic or low-toxic, and people will also feel uncomfortable when touching. In sealed containers or indoors, adequate ventilation is required.

    Features

    1) Applicable to any kind of materials except loose porous materials, suitable for surface defect detection of non-ferromagnetic materials.

    2) For work-pieces whose structure, shape and size are not conducive to magnetization, infiltration can be used.

    3) Unable to detect buried defects and closed defects.

    4) There are defects in several directions at the same time, only one flaw detection operation is needed for penetrant testing, and magnetization testing needs to be performed in at least two directions.
