Q:-When considering the advantages of site RT over UT which of the following applies?

Posted on

1. A permanent record produced, good for detecting defects which do not have significant depth in relation to axis of the X-ray beam and defect identification
2. A permanent record produced, good for detecting all surface and sub-surface defects and assessing the through thickness depths of defects
3. A permanent record produced, defect identification not so reliant on operator skill
4. No controlled areas required on site, a permanent record produced and good for assessing the extent of pipe wall thickness reductions due to internal corrosio
