Here at Southern NDT Services we can offer Radiographic Inspection and Dye Penetrant Inspection in the following sectors:
Nuclear
Oil and Gas
Aviation
Medical
General Manufacturing
Here at Southern NDT Services we can offer Interpretation of radiographs, that are carried out by our qualified personnel. This process enables identification of internal defects or features such as radiographic testing of welding joints, castings, forgings or composites. This process can also be used for corrosion and measurement of wall thickness.
Here at Southern NDT Services we can offer Level 3 Consultancy Services in Radiographic Testing and Dye Penetrant Testing.
Radiographic Testing (RT), also known as Radiographic Examination, is a non-destructive testing (NDT) method used to examine the internal structure of manufactured components. It helps identify any flaws or defects within the material without causing damage. Here are the key points about radiographic testing:
Ø Principle:
o The test part is placed between a radiation source (either x-rays or gamma rays) and a film or detector.
o The material density and thickness of the test part affect the amount of radiation that passes through it.
o Thicker and denser materials allow less radiation to pass through.
o The film records the radiation that reaches it, creating a radiograph.
o Defects within the material, such as cracks, porosity, or lack of fusion, appear as changes in density on the radiograph.
Ø Procedure:
o The test specimen is positioned between the radiation source and the film or detector.
o The radiation passes through the material, and the resulting radiograph captures any variations in thickness or defects.
o By analysing the radiograph, inspectors can identify flaws and assess the material’s integrity.
Ø Applications:
o Weld Inspection: Radiographic testing is commonly used to assess weld quality. It detects weld defects like cracks, porosity, and inclusions.
o Industries: RT is widely used in oil and gas, aerospace, transport, military, automotive, manufacturing, offshore, petrochemical, marine, and power generation industries.
o Component Inspection: It is used for assessing castings, forgings, pipelines, pressure vessels, and structural components.
Ø Advantages:
o High Dependability: RT is reliable for detecting internal defects.
o Non-Destructive: It doesn’t harm the material being tested.
o Wide Range of Applications: Suitable for various materials and components.
In summary, radiographic testing plays a crucial role in ensuring the quality and safety of critical components in various industries.
