  1. Under API 510, who has overall responsibility for ensuring that pressure vessels are inspected in accordance with the code?

    Answer: The owner/user of the pressure vessel

    API 510 places overall responsibility for a safe inspection program on the owner/user of the pressure vessel.

  2. When a pressure vessel is operated above its established MAWP, the immediate required action per API 510 is to:

    Answer: Take the vessel out of service and conduct an engineering review before restart

    Operating above MAWP requires immediate removal from service and an engineering review to determine fitness for service before resuming operation.

  3. In API 510's risk-based inspection (RBI) framework, 'risk' is defined as a function of:

    Answer: Probability of failure multiplied by consequence of failure

    In RBI, risk = probability of failure × consequence of failure, providing a basis for prioritizing inspection resources.

  4. Which of the following statements about pressure relief devices (PRDs) is correct under API 510?

    Answer: API 510 covers pressure vessels and considers PRDs as an integral part of the pressure-containing system

    API 510 recognizes pressure relief devices as part of the pressure-containing system protecting the vessel, though detailed PRD inspection guidance is in API 576.

  5. What is the significance of 'remaining life' in API 510 inspection interval calculations?

    Answer: Remaining life = (actual thickness − minimum required thickness) ÷ corrosion rate, and drives the maximum inspection interval

    Remaining life, calculated from corrosion rate data, is the primary driver for setting the next inspection interval under API 510.

  6. According to API 510, which type of weld is typically given the highest scrutiny during an internal inspection due to its stress concentration potential?

    Answer: Nozzle-to-shell welds and other discontinuity welds

    Nozzle-to-shell junctions and other geometric discontinuities create stress concentrations and are focal points for inspection per API 510 guidelines.

  7. API 510 allows inspection intervals to be extended beyond the normal limits under which condition?

    Answer: When an approved risk-based inspection (RBI) program per API 580/581 is implemented and documented

    A documented RBI program meeting API 580/581 requirements allows the owner/user to adjust inspection intervals beyond the standard API 510 limits.
