API Pressure Vessel Inspector Sample Questions:
After a vessel has been placed in service, what Code is used to evaluate?
- A. ASME Section V
- B. API 510
- C. ASME Section VIII
- D. API 572
Correct Answer: B 🗳️
Describe the considerations and procedures for pressure testing insulated pressure vessels under API-510.
Reveal Solution Discussion 0Correct Answer:
Pressure testing insulated pressure vessels under API-510 involves several considerations to ensure that the insulation does not conceal leaks or damage. Before testing, inspectors typically require that sections of insulation be removed to expose the vessel surface, particularly in areas prone to corrosion or wear. The testing itself, whether hydrostatic or pneumatic, must be conducted at pressures specified by API-510 to simulate operational conditions accurately. After testing, the insulation must be carefully replaced and inspected to ensure that it maintains its protective properties. Documentation of the entire process is crucial for future inspections and maintenance records.
Temporary repairs to pressure vessels:
- A. may remain in place permanently if approved by the pressure vessel engineer and the API authorized pressure vessel inspector.
- B. must be replaced with permanent repairs during the next scheduled shutdown.
- C. may remain in place for long periods if approved by the pressure vessel engineer.
- D. may remain in place for long periods if approved by the API-authorized pressure vessel inspector.
Correct Answer: C 🗳️
The re-rating of a pressure vessel will be considered complete only when the authorized pressure vessel inspector witnesses which of the following?
- A. The attachment of an additional nameplate of stamping
- B. The final painting of the vessel
- C. The pressure test required by the code
- D. The stamping of welds by each welder
Correct Answer: A 🗳️
Explain the API-510 provisions regarding the frequency and extent of inspections required after a pressure vessel has been altered or repaired.
Reveal Solution Discussion 0Correct Answer:
API-510 requires that pressure vessels undergo rigorous inspections following any repairs or alterations to ensure the integrity of the vessel is maintained. The standard stipulates that these vessels should be inspected immediately after the work is completed and before they are returned to service.
The type of inspection can vary but typically includes non-destructive testing (NDT) to verify the quality of the repair or alteration and to confirm that no additional damage was introduced during the process.
