When a crack is discovered in a vessel that is in a highly stressed area, what action should you recommend to be considered as a first step in any effort to correct the flaw?
- A . Call in a pressure vessel engineer
- B . Design an overlay patch to completely cover the affected area that has rounded corners
- C . Using an insert patch, to completely remove the affected area
- D . Removing the crack using by grinding and inspect using an NDE procedure before repair by welding
Describe the requirements and procedures outlined in API-510 for upgrading or modifying pressure relief systems on existing vessels.
The best description of Temper embrittlement is:
- A . Cracking due to operating at high temperatures above 650°F C 1100°F
- B . Cracking due to low temperature service
- C . Loss of ductility and notch toughness due to exposure above 650°F C 1100°F
- D . Flaking of the metal surfaces, causing dip pits due to exposure above 650ºF C1100°F
Explain how API-510 facilitates the upgrade of older pressure vessels to meet modern safety and efficiency standards.
API-510 requires a hydrostatic test to be performed at what interval during the vessel’s service life?
- A . After each shutdown
- B . Every 5 years
- C . Every 10 years
- D . Only after major repairs
Test or inspection intervals on pressure-relieving devices in typical process service should not exceed which of the following?
- A . Interval should not exceed 10 years
- B . Interval should not exceed 7.5 years
- C . Interval should not exceed 5 years
- D . Interval should not exceed 2.5 years
Widely scattered pits may be ignored as long as all but which of the following is true?
- A . No pit depth greater than 1/2 the vessel wall exclusive of the corrosion allowance
- B . Total area of pits does not exceed 7 square inches in any 8” diameter circle
- C . Sum of dimensions along a straight line does not exceed 2 inches
- D . No pit depth greater than 2/3 the vessel wall exclusive of the corrosion allowance
What documentation must be reviewed and updated after any major alteration or repair to a pressure vessel as per API-510?
- A . The original design documents
- B . The latest inspection report
- C . The vessel’s operating manual
- D . All relevant documentation, including design, operation, and maintenance
How does API-510 address the challenges of corrosion under insulation (CUI) for pressure vessels?
An in-service vessel is being repaired or altered.
If there is a conflict between the requirements of API 510 and the legal jurisdiction, which should be followed?
- A . API 510
- B . the legal jurisdiction
- C . the most stringent requirements
- D . either set of requirements based on engineer and AI approval
