What non-destructive inspection method can measure the wall thickness of closed vessels? a) Radiographic method b) Ultrasonic method c) Fluorescent penetrant method d) Magnetic particle method

UpStudy AI · Accepted Answer

To determine the appropriate non-destructive inspection method for measuring the wall thickness of closed vessels, let's analyze the options provided:

a) **Radiographic method**: This method uses X-rays or gamma rays to create images of the internal structure of an object. While it can provide information about the integrity of the material, it is not primarily used for direct wall thickness measurement.

b) **Ultrasonic method**: This method uses high-frequency sound waves to measure the thickness of materials. It is particularly effective for measuring the wall thickness of closed vessels, as it can provide accurate readings without needing to access the interior of the vessel.

c) **Fluorescent penetrant method**: This method is used to detect surface-breaking defects in non-porous materials. It does not measure wall thickness.

d) **Magnetic particle method**: This method is used to detect surface and near-surface defects in ferromagnetic materials. It is not suitable for measuring wall thickness.

Based on this analysis, the best choice for measuring the wall thickness of closed vessels is:

**b) Ultrasonic method**.
The ultrasonic method is best for measuring the wall thickness of closed vessels.
