  1. Under API 510, which document establishes the minimum inspection intervals for pressure vessels in a fixed equipment program?

    Answer: API 510 itself, supplemented by the owner/user inspection program

    API 510 sets the maximum inspection intervals, and the owner/user inspection program documents how those requirements are applied at the specific facility.

  2. What is the primary purpose of the 'fitness-for-service' (FFS) assessment referenced in API 510?

    Answer: To evaluate whether a damaged or degraded vessel can continue safe operation

    FFS assessments per API 579 determine whether equipment with flaws or degradation can remain in service safely.

  3. According to API 510, which of the following is NOT a recognized method for determining the remaining corrosion allowance of a pressure vessel?

    Answer: Visual inspection of external surfaces only

    Visual inspection of external surfaces alone cannot determine remaining wall thickness; volumetric methods like UT or RT are required for corrosion allowance assessment.

  4. In API 510 terminology, what does 'MAWP' stand for and what does it represent?

    Answer: Maximum Allowable Working Pressure — the highest permissible operating pressure for the vessel

    MAWP is the Maximum Allowable Working Pressure, the highest pressure at which the vessel is allowed to operate under current conditions.

  5. Which API 510 inspection category applies to the external visual inspection of pressure vessels that are insulated?

    Answer: An external inspection is performed on accessible areas; insulation removal is risk-based

    API 510 requires external inspection of accessible areas; insulation removal for corrosion-under-insulation (CUI) assessment is guided by risk-based criteria.

  6. What is the role of the 'authorized inspection agency' (AIA) as defined in API 510?

    Answer: An organization that employs authorized pressure vessel inspectors and conducts inspections on behalf of the owner/user

    An AIA is an organization that employs API-authorized inspectors and is authorized to perform inspections per API 510.

  7. When calculating the required shell thickness under API 510 using the internal pressure formula, which variable represents the joint efficiency?

    Answer: E

    In the ASME Section VIII formula t = PR/(SE - 0.6P), E is the joint efficiency (or weld joint factor).
