SEE BENEATH THE SURFACE WITH DIGITAL RADIOGRAPHY TESTING
Digital radiography testing is a standard method for non-destructive testing and examining underlying features feasible for all industry sectors. It is essential for assessing piping, pressure vessels, and valves for defects and discontinuities in the marine and offshore industry. The testing technique benefits the non-destructive testing community, including real-time applications, improved detail detectability and lowered inspection times.
X-ray source penetrates through the sample of various densities, and the attenuated X-ray beam then forms a latent image on the digital detector. This testing technique detects discontinuities in multiple materials, including aluminium, steel, plastics and composites. It can be used for volumetric flaws or inclusion detection for deployed and commercialised products.
It is an advanced technology based on digital detector systems in which the x-ray image is displayed directly on a computer screen without the need for developing chemicals or intermediate scanning. The incident x-ray radiation is converted into an equivalent electric charge and then to a digital image through a detector. These readouts can be filtered and enlarged to enhance defect detectability.
It is used for non-destructive testing and examination of the internal features for all industry sectors.
It is used for assessing piping, pressure vessels and valves.
The testing technique is used for volumetric flaw detection.
X-ray source penetrate through the sample of various density and the X-ray beam attenuated then hits the digital detector.
This testing technique can detect discontinuities in a range of materials including aluminum, steel, plastics and composites.
Case Study :
Client Introduction:
Antique collector
pROBLEM
Those antique vessels were hauled from an auction. Our client was interested in validating the authenticity of the antique collection made with ancient bronze casting techniques. Due to the value of these specimens, they have to be analysed non-destructively.
Solution
Ancient bronze casting technique utilises the piece mould process, and the hollow internals is made using clay cores, which are held up by chaplets. The authenticity may be determined by determining the bronze chaplets with customised shape within the base of the vessel. Hence, X-ray Digital Radiography was performed to validate these vessels.
Review
Digital Radiography is an efficient, quick, and easy way to analyse a specimen with real-time feedback through a computer screen. A permanent digital radiograph can be stored digitally on any storage device to ensure the integrity of the radiograph quality over time.
Advantages of digital radiography testing
