Advanced nondestructive technologies, compared to the traditional methods, use more advanced equipment, technology, and complex processes. The advantages of NVI’s advanced radiography services are clear—shorter exposures translate into increased safety and decreased downtime. NVI offers Advanced Radiography testing to all materials that need NDT inspection to meet the compliance codes, standards, regulations or your company’s specifications.
- X-Ray Pipeline Crawlers
The X-Ray Pipeline Crawler is utilized when conditions are harsh, difficult or dangerous to human inspectors. This method remotely operated by a trained technician is used to observe the status of the weld in long-distance pipelines as well as speeds up the process of inspecting welds using conventional film. These crawlers produce a higher-quality image compared to gamma rays used in traditional radiography and require a smaller barricaded area and a shorter shot time.
- Computed Radiography
Computed Radiography is a form of digital radiography that uses a reusable imaging plate in the place of film. Once the plate is exposed, it is scanned, and the image is captured, which then is transferred to the high-depth monitor designed solely for viewing the quality of the weld. The screen plays a huge role in this process because the sharpness of the image relies on the monitor’s resolution. After about a minute, the images are ready to be evaluated. This method allows for a wider dynamic range and enhanced measurements for corrosion that is not possible with conventional film. Compared to traditional radiography, this approach is faster and offers more convenient and reliable ways to replace film. Some of the advantages of computed radiography include a reduction of retakes, the long lifespan of the imaging plates, the image quality, as well as many others.
- Real-Time Radiography
Real-time Radiography is the fastest and safest form of radiography. Rather than film or an imaging plate, real-time digital radiography uses a detector panel. As a result, technicians can examine the image in real time and add exposure time if it would improve image quality. As with computed radiography, images can be recorded electronically, sparing clients the need to store large volumes of film and making retrieving information much simpler.
