API 510 Closed Book Practice Exam Questions with Verified Answers

API 510 says that widely scattered pitting can be ignored provided that the: remaining thickness is not less than 1/2 the minimum required thickness. Rupture disks are commonly used to protect a pressure relief valve from corrosive products. When repairs and alterations are being conducted, which individual or organization is responsible Repair Organization Which code provides requirements for Hot Tapping? API 2201 Catalytic reformer vessels may have creep damage if the operating temperature is above: 900°F The maximum inspection interval for a pressure relief device in normal service is based on: acceptable performance of the device with a maximum interval of 5 year.A carbon steel vessel in caustic service has a temperature excursion up to 425°F. The vessel wall is 1/2" thick. No PWHT has been performed. What type of deterioration could be expected? Stress corrosion cracking During a vessel repair or alteration, when can controlled deposition welding be used as an alternative for post weld heat treating? For P1, P3, & P4 materials All RBI assessments must be: thoroughly documented. Once vessel repair work is complete, who should approve the finished work? Authorized inspector Which of the following activities is not included in the scope of API 510? Operating a vessel Which type of corrosion is most easily missed by a visual examination? Uniform corrosion The maximum allowable working pressure of a vessel is the: maximum pressure permitted at the top of the vessel.The use of a fillet weld patch on a vessel's pressure boundary requires approval from the: Authorized inspector and the pressure equipment engineer During alterations, fabrication approvals (hold points) shall be designated by: authorized inspector Per API 510, a PRV repair organization must: Have a fully documented quality assurance system and training program During vessel repairs or alterations, welding records shall be: Available to the authorized inspector Repairs Of vessel cracks at a serious stress concentration requires approval by: pressure vessel engineer The seating surfaces on a relief device must have a flatness of: 3 light beads/bands An "F" on the radiograph indicates: The IQI is placed on film sideAn inspector is evaluating a corroded area on the vessel per API 510. The area is marked off in a grid with five longitudinal lines. Multiple thickness readings are taken on each longitudinal line. When performing remaining life calculations for this corroded area, the current thickness reading to use in the calculation is the: Average thickness of the longitudinal line with the lowest average API 510 takes effect: Once the vessel is placed in service Erosion or corrosion in an exchanger shell that is adjacent to the bundle baffles can be most easily found during an internal inspection with: Flashlight beam directed parallel to the shell's internal surface During a vessel repair, if a preheat is substituted for a post-weld heat treatment, who is required to review this substitution? Pressure vessel engineer Which of the following is NOT an acceptable method for repairing a locally thinned area that is below acceptable thickness? Instal
