Non-Destructive Testing (NDT)

Non-destructive testing services that detect flaws in materials and welds in industrial facilities, pipelines and power plants without causing any damage.

Non-Destructive Testing (NDT) is the collective set of inspection methods used to detect discontinuities, defects and flaws on the surface and inside a material or component without taking it out of service or damaging its physical integrity. Methods such as radiographic, ultrasonic, magnetic particle, penetrant and visual testing are selected according to the material type and the kind of defect sought.

TÜV AUSTRIA SILA KALİTE provides NDT services including radiographic testing, ultrasonic testing, magnetic particle testing, penetrant testing, eddy current testing, visual testing, leak and pressure testing, positive material identification and ferrite content measurement with its experienced staff and advanced equipment.

Related services

Radiographic Testing

A method that uses X-rays or gamma rays to image internal voids, thickness and density of a material on radiation-sensitive film.

View details

Ultrasonic Testing

A method that determines the location and type of discontinuities using the reflections of high-frequency sound waves inside the material.
