Dye Penetrant Testing Agent | High Sensitivity Level 2, Water Removable
Dye penetrant testing is one of the simplest and most effective nondestructive testing methods. It provides unique advantages in detecting surface-breaking defects that affect the service life of metallic and non-metallic components as well as the safety of pressure vessels, including welding cracks, fatigue cracks, stress corrosion cracks, grinding cracks and quenching cracks. It features high detection sensitivity, fast results, good repeatability and intuitive display. Due to these merits, dye penetrant testing plays an increasingly important role in quality assurance systems across industries such as machinery, metallurgy, petroleum, chemical engineering, railway, transportation, shipbuilding, mining, construction, aviation, aerospace, power generation, pressure vessel manufacturing and national defense.
Dye penetrant testing materials can be completely removed with water, resulting in low testing costs. They are especially suitable for flaw detection on rough surfaces of raw materials and large components, with a minimum sensitivity of Level 2 (intermediate). This product is applicable to penetrant testing of rough surfaces such as castings, forgings, plates, bars and other metal raw materials, large parts and structures requiring Level 2 sensitivity, used in chemical, shipbuilding, railway, petroleum, heavy machinery, metallurgy, military and pressure vessel industries.
Operation Procedure
Pre-cleaning: Thoroughly remove all contaminants such as scale, rust, grease, etc., from the workpiece surface using a cleaning agent.
Penetrant application: Let the workpiece and test block dry for 5–10 minutes, then apply penetrant. Hold the nozzle 20–30 mm away from the surface. Apply penetrant as instructed, usually for 5–15 minutes, ensuring the test surface is fully wetted.
Cleaning: Remove excess penetrant from the workpiece surface using cleaning agent or water (water pressure ≤ 1.5 kg/cm²).
Developing: After fully mixing the developer, spray it evenly from a distance of about 300 mm. Defects will become visible shortly after development.
Post-inspection cleaning: Remove the developer using cleaning agent or water after inspection.
Handle and preserve the workpiece in accordance with process requirements.
Product Features
Fast penetration and clear, rapid imaging;
Suitable for solvent cleaning or water pre-cleaning followed by solvent cleaning;
Lower fluorine, chlorine and sulfur content than similar products, suitable for testing conventional austenitic stainless steel components;
High flaw detection sensitivity;
Free of toxic, harmful or highly irritating organic solvents;
Equipped with imported COSTER large-bore valve actuators providing fan-shaped spray, with uniform spraying, wide coverage, no clogging and comfortable operation. Interchangeable P, R and D nozzles are available.
Application Scope
This product is widely used for flaw detection in chemical, shipbuilding, power generation, aviation, machinery, automotive, metallurgy, railway and pressure vessel industries.
