API 570 — Piping Inspector Pipe Practice Questions

A piping inspector notices signs of corrosion on a carbon steel pipe. Which action should be taken first?

• AA. Measure wall thickness
• BB. Conduct a visual inspection
• CC. Replace the pipe
• DD. Review historical data

A pipe's integrity is questioned due to its exposure to a corrosive environment. Which factor is most critical in this assessment?

• AA. Flow rate of the fluid
• BB. Type of insulation used
• CC. Temperature of the pipe
• DD. Duration of exposure to corrosion

An inspector finds that a section of pipe is experiencing excessive vibration. What is the best course of action?

• AA. Monitor the situation
• BB. Conduct a root cause analysis
• CC. Ignore it, as it is probably normal
• DD. Schedule immediate repair

If a pipe's wall thickness is reduced by corrosion, how does that affect the pressure rating?

• AA. Decreases the pressure rating
• BB. Depends on the fluid type
• CC. No effect on the pressure rating
• DD. Increases the pressure rating
