Radiometric Profiling vs Industrial Radiography for Refrigeration Piping

What is the right NDT technology to evaluate your ammonia refrigeration system?

This video reviews the performance of two non-destructive testing methods, Radiometric Profiling (RP) vs. Industrial Radiography (RT) for refrigeration piping.

Printable Comparison - RP and RT

Much like a familiar medical x-ray, conventional Industrial Radiography testing uses radiation to capture an image, or an x-ray, of the pipe. An x-ray film or a digital plate is located near the pipe to be inspected and an x-ray or gamma ray energy source is located some meters away. The film or digital plate is then exposed to the radiation, resulting in an x-ray image of a portion of the pipe.

For radiography testing, safety regulations require that a safe working area be established during the creation of the images. This often means that a barrier will be identified. All personnel inside of the boundaries of the barrier will need to be evacuated during the exposure, including those on floors above and below.

Radiography is often followed by a second NDE/NDT method to further investigate areas of vulnerability identified by the evaluation.

When determining the best method for your industry and company requirements, there are many factors that should be evaluated. To learn more about Industrial Radiography for refrigeration piping and other available NDT methods, click here.
