Radiographic Testing (RT) is a non-destructive testing method that uses X-ray or gamma radiation to create images of a pipeline’s internal structure — revealing corrosion, cracks, weld defects, inclusions, and wall thickness variations.

Radiographic Testing (RT) is a non-destructive testing method that uses X-ray or gamma radiation to create images of a pipeline’s internal structure — revealing corrosion, cracks, weld defects, inclusions, and wall thickness variations. RT provides a permanent film or digital record of the inspection, making it valuable for quality documentation.

RT is commonly used for pipeline girth weld inspection during construction and for in-service assessment of localized defects. However, it requires access to both sides of the pipe (or use of panoramic exposure techniques), radiation safety protocols, and certified personnel.

For comprehensive buried pipeline inspection without radiation exposure or excavation, EMPIT’s CMI technology provides non-invasive aboveground corrosion detection and integrity assessment — complementing RT for areas where radiographic access is impractical.
