Gamma Positioning Tool (OPG)
Push the limits of precision in industrial radiography!!!
The OPG is an innovative instrument specifically designed to optimize the positioning of the radioactive source or collimator during controls by industrial radiography or industrial gammagraphy in the demanding field of Non-Destructive Testing (RT). This positioning accessory or collimator support ensures the immobility and precise positioning of the source, thus allowing for exact localization and repeatable control results. The operational efficiency provided by the OPG translates into time and money savings for companies, all while maintaining the integrity and accuracy of inspections. Its robust and functional design makes the OPG an essential ally for all NDT professionals, wishing to increase the productivity and reliability of their industrial gammagraphy operations.
Context and field of application
In the demanding field of Non-Destructive Testing (NDT RT) by industrial radiography and industrial gammagraphy, the accuracy and stability of the radioactive source positioning are crucial to ensure the quality and reliability of the inspections. Gamma clamps or ellipse clamps, primarily serving as collimator supports, are indispensable tools to guarantee the precision of the controls, the immobility of the source, and accurate localization.
These specialized tools are essential in sectors such as the petrochemical industry, shipbuilding, energy production, and aeronautics, where every detail matters. They afford operators the ability to position the source quickly and accurately, which translates to significant time and money savings for companies. The repeatability of the control, ensured by the use of these accessories for gammagraphy, also contributes to the optimization of the inspection processes, thereby enhancing confidence in the safety and quality of the inspected structures and components.
Guide sur la gammagraphie industrielle
Industrial Gammagraphy (Industrial Radiography Testing, RT) is a method of Non-Destructive Testing (NDT) that employs ionizing radiation to examine the integrity and the internal structure of materials. This technique is widely used in sectors such as aerospace, oil, construction, and metal manufacturing to detect defects such as cracks, inclusions, porosities, and other anomalies that cannot be seen on the surface.
Principle and importance of accessories
Using ionizing radiation from sources such as iridium-192 or selenium-75, this method creates radiographic images that reveal the internal structure of materials. Source positioning accessories like gamma clamps or ellipse clamps are crucial for precisely placing the radioactive source and obtaining clear and detailed images.
- Sample preparation :
Cleaning and accessibility of the object are essential. Source positioning accessories are used to prepare the sample.
- Source positioning :
Thanks to ellipse clamps for gammagraphy and accessories for gammagraphy, the source and the detector are optimally positioned on either side of the object.
- Exposure :
The source, well-positioned using clamps for gammagraphy, emits radiations to create an image on a film or a digital detector.
- Interpretation :
The obtained images are then examined by a specialist to identify any anomalies and assess the quality of the components.
Industrial gammagraphy is vital for ensuring quality and safety in the industry. It allows for the early detection of defects, thus minimizing the risks of failure and extending the lifespan of the components.
Adherence to AFNOR standards such as NF EN ISO 5579, NF EN 12681, and NF EN ISO 17636 is fundamental to ensure the quality and consistency of results in industrial gammagraphy. These standards guide NDT professionals in the application and interpretation of radiographic methods.
In summary, the use of specific accessories and adherence to current standards are key elements in the success of industrial gammagraphy inspections, thus contributing to safety and quality in the industry.
