Radiographic inspection (RT) is a crucial non-destructive testing (NDT) method used to detect internal flaws and imperfections in pipes. This powerful technique utilizes penetrating radiation to create images revealing the internal structure, allowing for the identification of defects that could compromise the integrity of the pipeline. This comprehensive guide delves into the intricacies of radiographic inspection in pipes, covering its applications, techniques, advantages, limitations, and safety protocols.

Understanding the Principles of Radiographic Pipe Inspection

Radiographic inspection relies on the principle of differential absorption of ionizing radiation. A source of radiation, typically X-rays or gamma rays, is directed at the pipe. The radiation passes through the pipe, and its intensity is reduced depending on the density of the material. Denser areas, like the pipe’s base metal, absorb more radiation, while less dense areas, such as defects like cracks, porosity, or inclusions, absorb less. The resulting differential absorption is captured on a film or digital detector, creating a radiograph—a shadow image revealing internal structures and flaws.

The choice between X-rays and gamma rays depends on factors such as the pipe’s thickness, material, and the required level of detail. X-ray sources are more versatile and offer better control over radiation output, while gamma ray sources are more portable and suitable for field inspections of thicker sections.
