What determines the inspection interval for pressure vessels under API 510?
Answer: The lesser of half the remaining life or 10 years
API 510 sets internal inspection intervals at the lesser of half the estimated remaining life or 10 years, with a minimum of the corrosion rate-based interval.
What is risk-based inspection (RBI) in the context of API 510?
Answer: Prioritizing inspection activities based on risk assessment of likelihood and consequence of failure
RBI uses risk assessment to prioritize inspection resources toward equipment with the highest risk of failure and greatest consequences.
What information should be reviewed before conducting a pressure vessel inspection?
Answer: Previous inspection reports, operating history, and maintenance records
Reviewing previous reports, operating history, and maintenance records identifies known issues, trends, and areas requiring special attention.
What is an on-stream inspection?
Answer: Inspection performed while the equipment remains in service
On-stream inspection is performed while equipment remains in service, using NDE techniques that do not require shutdown or entry.
How should inspection findings be documented and tracked?
Answer: In formal reports with measurements, photos, and recommendations maintained in equipment files
Formal documentation with measurements, photographs, and recommendations creates a permanent record for trending and future reference.
What triggers an unscheduled inspection of a pressure vessel?
Answer: Process upsets, unusual operating conditions, or suspected damage
Unscheduled inspections are triggered by abnormal events such as process upsets, overpressure incidents, or suspected damage requiring immediate evaluation.
