Managing the Integrity of Insulated Equipment: The Right Non-Destructive Examinations

September/October 2018 Inspectioneering Journal

The challenge to find CUI is difficult and one single NDE technique cannot be used to identify it. This remains the case today as we combine NDE techniques to perform CUI assessments. The techniques and strategies commonly used today are summarized...
Automated Radiographic Testing: High-Speed Corrosion Mapping Using Robotic Crawlers

July/August 2023 Inspectioneering Journal

The capabilities of automated radiographic testing (ART) make it the preferred method to manual techniques for detecting piping corrosion defects in the field.
NDT Inspections of HF Acid Lines in Alkylation Units

March/April 2015 Inspectioneering Journal

This article provides a discussion of a recent inspection performed at a U.S. refinery. Industry HF lines are experiencing piping failures in increasing numbers due to the presence of residual elements entrained within their carbon steel components.

When it comes to Digital Radiographic Testing (RT), there are two main technologies: Computed Radiography (CR) and Digital Detector Arrays (DDA/DR). Both CR and DDA have pros and cons, so neither can be said to be the superior technology—the target application is crucial. Therefore, it is extremely important to know the strengths and weaknesses of both in order to select the right technology for achieving the best results and return on investment for the specific application. This webinar replay will provide insights into the functionality and technologies in general, as well as their suitability in specific applications.
