Radiography using digitally captured media is a powerful Non-Destructive Testing (NDT) technique that allows clients to identify and investigate a large number of asset integrity concerns efficiently and non-intrusively.
Digital Detector Array (DDA) produces a radiographic image relayed rapidly to a monitoring and data collection system using highly-efficient GOS (Gadolinium oxysulfide [Gd2O2S]) scintillatorbased detectors and the GE Rhythm™ software package. Rapid provision of images supports timely interpretation and decision making capability before leaving the worksite. The system has an optional wireless mode for transmission of images.
Computed Radiography (CR) provides a reliable, cost-effective alternative to conventional film and employs flexible, reusable phosphor plates (screens) to capture images. The exposed phosphor plates are digitally scanned, creating a saved digital image which can be displayed for interpretation. Images can be manipulated and filtered to improve visual representation and highlight areas of concern.
Applications
Digital Radiography is used for many industrial applications and provides a safe, rapid, and environmentally-friendly inspection technique.
- Weld inspection
- Confirmation of wall thickness
- Identification of corrosion and erosion
- Detection and measurement of corrosion scabs
- Detection and assessment of blockages in pipes
- Corrosion Under Insulation (CUI)
- Valve operational issues
- Blockages in pipes
- Liquid – vapor interfaces
Benefits
- More precise imaging with greater picture enhancement.
- The ability to view multiple thickness areas in one exposure.
- Reduced costs, with no chemical or silver recovery required, through digital-image processing.
- Faster turnaround time.
