Liquid Dye Penetrants > Red Dye Penetrants
ORION series of dye penetrant flaw detection materials consist of a RED DYE PENETRANT, DEVELOPER AND PENETRANT REMOVER/CLEANER. It is used for the detection of surface defects of all kinds of material. In this process the inspection is carried out under normal light.
Red Dye Penetrant :
Brilliant red mobile fluid with very low surface tension and capillary action.
Penetrant Remover :
Solvent based, volatile liquid that cleans and removes grease and other types of dirt and also removes excess penetrant from the surface.
Developer :
Solvent based, volatile liquid suspension containing very fine white powders. It is used for drawing out the penetrant from the defects onto the surface of the component under inspection and provides an uniform white background for maximum contrast. Bright red indications of the defects are revealed clearly on the surface.
FEATURES
  • Quickly and acurately locates surface defects which are otherwise invisible to the naked eye
  • Non-corrosive to all types of metals
  • Non-toxic
  • High area coverage
APPLICATIONS
  • Castings : Surface Porosity Cold shuts etc.
  • Forgings : Laps, cracks, bursts etc.
  • Weldments : Cracks, Pores etc.
  • Metallic Materials : Fatigue racks, Grinding cracks, Heat treatment cracks etc.
  • Tanks, pipes : Through-leaks.
  • Carbide Tips & Tools : Cracks, lack of bond.
  • Non-metallic Materials : Plastics, ceramics, glass etc.
INSTRUCTIONS
PRE-CLEANING APPLY PENETRANT REMOVE PENETRANT DEVELOPING INSPECTION
Remove dirt, grease and dust from the surface with penetrant remover. Apply Red Dye Penetrant on the surface to be tested and allow to dwell for five to twenty minutes. Wipe off the excess penetrant with a cloth dampened with remover. Apply Developer uniformly over the surface. Defects, flaws will be visible as bright red indications.
