Petronorm delivers non-destructive testing that examines material without affecting its integrity — visual, ultrasonic, magnetic particle and penetrant inspection, plus welding & material technologies, performed to ASME and EN standards.
Non-destructive testing is a method of examination which does not affect the integrity of the inspected material. Every technique below is carried out by expert staff in accordance with national and international standards.
The fastest and most economical NDT method — and the one that must be applied before all others. Performed by eye with auxiliary aids: magnifying glass, light source, camera and mirror devices.
Service detailsHigh-frequency sound waves are transmitted into the material and reflected back. A discontinuity changes the attenuation and shows up as an error echo — revealing the flaw and its location.
Service detailsDetects defects exposed at the surface or just below it. Magnetic flux or current applied to the surface creates leakage flux at a discontinuity, made visible with background paint and iron powder.
Service detailsA surface-defect method limited only by material type — steel, ceramics, glass and plastic can all be tested. Only defects open to the surface are found, so thorough pre-cleaning is essential.
Service detailsAnalysis, testing and certification of welding methods, personnel and materials — WPS/WPQR/WPQ, supervision of mechanical and NDT tests, EN 10204-3.2 certification and remaining-life assessment.
Service detailsSend us the material, the weld and the standard you work to — we will recommend the right examination and scope of testing.
