Describe the process for re-certifying a pressure vessel that has been out of service for an extended period according to API-510.
Reveal Solution Discussion 0Correct Answer:
Re-certifying a pressure vessel that has been out of service according to API-510 involves a comprehensive inspection and testing process to ensure it meets all current safety standards before being returned to service. This includes a complete internal and external visual inspection, thickness measurements to check for corrosion or erosion, and non-destructive testing to detect any defects.
Additionally, a hydrostatic or pneumatic test must be conducted to verify the integrity of the pressure boundaries. Any issues identified must be repaired, and the vessel must comply with the current versions of the API-510 code before re-certification can be completed.
Under API-510, how often must the qualifications of a pressure vessel inspector be revalidated through testing or continuing education?
- A. Every 10 years
- B. Every 5 years
- C. Every 3 years
- D. Every 6 years
