  1. The National Board Inspection Code (NBIC) is primarily used in conjunction with API 510 for which purpose?

    Answer: Governing repairs and alterations to pressure-retaining items

    The NBIC (ANSI/NB-23) provides rules for inspection, repair, and alteration of pressure-retaining items after they leave the original manufacturer.

  2. Under API 510, an 'alteration' to a pressure vessel differs from a 'repair' in that an alteration:

    Answer: Changes the vessel from its original design configuration

    An alteration changes the vessel's design intent, pressure rating, or configuration, whereas a repair restores a vessel to a suitable condition without changing design intent.

  3. According to API 510, what document must be prepared and retained after completing an alteration to a pressure vessel?

    Answer: An alteration report filed with the National Board

    Alterations require an alteration report (typically NB Form R-2 or equivalent) that must be filed with the National Board and retained by the owner.

  4. Which API standard specifically addresses Risk-Based Inspection (RBI) methodology for pressure vessels?

    Answer: API 580 and API 581

    API 580 provides RBI principles and API 581 provides the detailed risk-based inspection technology methodology for pressure vessels and piping.

  5. In API 510, the term 'corrosion allowance' refers to:

    Answer: Extra material thickness added at fabrication to account for future corrosion

    Corrosion allowance is additional thickness built into the vessel design at fabrication to account for anticipated metal loss during the vessel's service life.

  6. When performing a hydrostatic test per ASME Section VIII Division 1, the test pressure is typically:

    Answer: 1.5 times the MAWP (adjusted for temperature)

    ASME Section VIII Division 1 requires hydrostatic test pressure of 1.5 times MAWP, adjusted for the ratio of allowable stresses at test vs. design temperature.

  7. Under API 510, pressure vessels subject to internal corrosion shall have the remaining corrosion allowance measured to determine the:

    Answer: Remaining life and next inspection interval

    Thickness measurements are used to calculate remaining life (remaining corrosion allowance ÷ corrosion rate), which then drives the next inspection interval.
