Pressure Vessel Inspector (API-510) Free Practice Test

Question 1

What does API-510 require to verify a welder's qualifications when welding on a pressure vessel?

A. A practical demonstration

B. Inspection of previous work

C. A written test

D. Performance qualification records

Correct Answer: D

Question 2

What action is required under API-510 if a pressure vessel's corrosion rate exceeds expected values?

A. Recalculation of the vessel's remaining life

B. No specific action required

C. Immediate shutdown

D. Notification of the API

Correct Answer: A

Question 3

How does API-510 address the challenges of inspecting pressure vessels in remote or hazardous locations?

Correct Answer:

API-510 addresses the challenges of inspecting pressure vessels in remote or hazardous locations by allowing for the use of advanced remote inspection technologies. These include robotic inspection devices, drones equipped with cameras and sensors, and remote non-destructive testing techniques that can be operated from a distance. These technologies help in conducting thorough inspections without compromising the safety of inspectors. Additionally, API-510 encourages the development of inspection plans that specifically consider the logistical and safety challenges associated with remote or hazardous environments.

Question 4

The internal inspection interval must be reviewed whenever changes occur that could affect the degradation of the vessel.
In which of the following situations does a review of the internal interval need not be conducted?

A. operating pressure decreases

B. operating temperature increases

C. fluid composition changes

D. operating pressure increases

Correct Answer: A

Question 5

According to API-510, which type of record must be permanently maintained for a pressure vessel?

A. Inspection records only

B. Repair records only

C. Only the most recent inspection record

D. All records related to the vessel's design, fabrication, inspection, and repairs

Correct Answer: D

Question 6

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

Correct Answer: D

Question 7

When discussing repairs to a pressure vessel what is the definition of 'construction codes'?

A. The Code the vessel was constructed to including non-standard and jurisdictional special vessels

B. The API 510 Code

C. The NBIC

D. The current ASME Code edition

Correct Answer: A

Question 8

Who determines if a temporary fillet weld patch may be used in a repair?

A. The API authorized inspector

B. Any of these

C. A repair organization which holds a valid NBIC R stamp

D. An engineer competent in pressure vessel design and the API authorized inspector

Correct Answer: D

Question 9

API-510 requires a hydrostatic test to be performed at what interval during the vessel's service life?

A. Every 10 years

B. Only after major repairs

C. After each shutdown

D. Every 5 years

Correct Answer: B

Question 10

Which factor is not considered when determining the inspection intervals for pressure vessels according to API-510?

A. Previous paint color

B. Vessel age

C. Vessel location

D. Service history
