What is the method?
Close Proximity Radiography is a specialised radiographic technique used where the radiation source and image receptor are positioned close to the component because conventional radiographic geometry cannot be achieved due to restricted access or congestion.
Application
Close Proximity Radiography is a specialised radiographic technique used where the radiation source and image receptor are positioned close to the component because conventional radiographic geometry cannot be achieved due to restricted access or congestion.
Key Benefits
- Allows radiographic inspection in restricted and congested locations.
- Useful during shutdowns, brownfield work, and field modifications.
- Supports weld inspection and local corrosion evaluation.
- Reduces the need for extensive plant rearrangement to achieve access.
Inspection Capabilities
- Enables radiographic examination in restricted geometries where conventional source placement is not possible.
- Particularly useful for closely spaced piping and difficult tie-in locations.
- Provides an internal imaging option where geometry challenges would otherwise prevent RT application.
- Offers a practical solution for highly congested operating plant environments.
Limitations
- Subject to all radiographic safety requirements.
- Image quality depends heavily on geometry and setup precision.
- Scatter and geometric unsharpness may affect image quality.
- Complementary UT or PAUT may still be required for full evaluation.
