What is the recommended scanning rate for corrosion evaluation?

• A. Faster than 10 in./sec.
• B. Slower than 6 in./sec.
• C. Up to 8 in./sec.
• D. Exactly 5 in./sec.

Answer: (B)

The recommended scanning rate for corrosion evaluation is slower than 6 inches per second. This slower scanning rate allows for more accurate and reliable data collection when assessing the condition of piping system components for corrosion. When scanning at a slower pace, inspectors can achieve better resolution in the data they collect, which is crucial for identifying potential issues such as pitting, wall thinning, and other forms of corrosion. Moreover, it minimizes the risk of missing critical defects that may not be apparent if the scanning is done too quickly. A careful and methodical approach ensures that the evaluation aligns with the standards set in API 574, which emphasizes the importance of thorough inspections.
