Our rope access technicians follow the rigorous safety standards of the Canadian Nuclear Safety Commission and the International Rope Access Trade Association. We are experienced in conducting radioactive testing for all manner of industrial purposes.
Used extensively in the petroleum, chemical and nuclear industries as well as fabrication and consumer goods, radiographic testing is a non-destructive form of examination that provides vital details about interior compositions. The testing uses gamma radiation to detect structural faults in materials such as metal and concrete. It is widely used for inspecting welds, large cables, pipelines and industrial materials. It has also been applied to monitor the internal state of furnaces, as radiographic testing is suitable for high heat usage.
Benefits of Radiographic Testing
Gamma rays or x-rays are directed through the object to provide an image of any imperfections of weaknesses in the internal composition of the item, component or material. Radiographic testing requires access from both side and produces an image on film, much like an x-ray. It is an excellent method for inspecting for internal defects of critical components without causing any damage. It can be used to:
- Inspect materials and assembled components internal composition for flaws
- Sense changes in thickness corrosion, voids, cracks and material density changes.
- Detect both surface and subsurface defects
- Measure dimensions and angles without sectioning
Compared to other methods of Non-Destructive Examination, radiographic testing does require some additional safety measures.
Checking new natural gas or oil pipeline systems with gamma radiography is standard industry practice. Radioactive gauges are also essential for measuring density and liquid levels in the petroleum industry. The most common usage of radiographic testing is to inspect the welds of high pressure and large diameter pipelines. Radiographic testing is regularly used for quality checks on these structures.
