  1. API 510 states that the authorized pressure vessel inspector must be certified by:

    Answer: The National Board of Boiler and Pressure Vessel Inspectors or an equivalent jurisdictional authority

    The API 510 authorized inspector must be certified by the National Board or a recognized jurisdictional authority, and must hold a valid API 510 certificate.

  2. Under API 510, which of the following is the correct approach when actual corrosion rates differ significantly from previously assumed rates?

    Answer: Recalculate remaining life and adjust the inspection interval accordingly

    When actual corrosion rates differ from previous estimates, the remaining life calculation must be updated and the inspection interval revised to reflect current conditions.

  3. According to API 510, the maximum allowable working pressure (MAWP) of a vessel is based on:

    Answer: The weakest pressure-containing element calculated per the applicable construction code

    MAWP is determined by the weakest pressure-containing component of the vessel, calculated per the applicable code at the governing conditions.

  4. When API 510 refers to 'pitting' as a damage mechanism, how should an inspector evaluate scattered pitting for fitness-for-service?

    Answer: Apply API 510 Annex B pitting charts or an equivalent FFS methodology

    Scattered pitting should be evaluated using the pitting charts in API 510 Annex B or an equivalent FFS method, considering pit density and remaining ligament thickness.

  5. API 510 requires that inspection results and thickness data be retained for how long?

    Answer: Until the vessel is retired or transferred to a new owner

    API 510 requires that inspection records be retained for the life of the vessel; when ownership transfers, records must accompany the vessel.

  6. Under API 510, if a repair organization lacks the applicable ASME code stamp, they may perform pressure vessel repairs only if:

    Answer: They hold a National Board 'R' stamp repair certificate

    Organizations performing pressure vessel repairs must hold a National Board 'R' stamp or equivalent authorization recognized by the jurisdiction.

  7. According to API 510, which inspection method is specifically recommended for detecting hydrogen-induced cracking (HIC) in wet H₂S service?

    Answer: Ultrasonic testing (UT) using shear wave or phased array techniques

    Shear wave UT or phased array UT is recommended for detecting HIC and stepwise cracking because these techniques can identify planar flaws parallel to the vessel wall.
