Dye penetrant testing

Dye penetrant testing (PT) method is based on penetration of liquid penetrant into open surface discontinuities. PT is not applicable on high porous materials.

Dye penetrant method is applicable for surface defects determination: surface cracks, pores, lack of fusion, inter-granular corrosion, etc.

Dye penetrant testing is performed on welds and parent material of all potentially dangerous installations.

Testing standards: LST EN ISO 3452-1:2013, PNAE G-7-018-89, GOST 18442-80.

Certified personnel: 41 PT level 2 specialists certified according to LST EN ISO 9712.

MR-Chemie or Pfinder Chemie detection media is used for PT.
