Attending an interview for a Pressure Vessel Inspector? Here are some essential questions to anticipate.
Syed Fadzil Syed Mohamed
Fellow of The Institution of Engineers, Malaysia (FIEM)
It is critical to prepare for an interview as a pressure vessel inspector in order to demonstrate your knowledge and expertise in the field. I've included a detailed list of ten critical questions to prepare for, as well as suggested answers and explanations for each:
??
1. What does a pressure vessel inspection serve?
Answer: The primary purpose of a pressure vessel inspection is to ensure the integrity and safety of the pressure vessel. Inspections aid in the detection of potential defects, damage, or signs of deterioration that could jeopardise the structural integrity of the vessel and result in dangerous situations.
Explanation: This question is intended to assess your comprehension of the primary purpose of pressure vessel inspections. Your response should emphasise the importance of safety and the need to identify and address potential issues as early as possible.
?
2. What are the essential components of a pressure vessel inspection?
Answer: A thorough pressure vessel inspection includes evaluating the vessel's shell, heads, nozzles, welds, supports, pressure relief devices, insulation, and internal surfaces. Non-destructive testing (NDT) techniques such as ultrasonic testing, radiography, and magnetic particle testing may also be used during inspections.
Explanation: This question tests your understanding of the various components that must be inspected during a thorough examination. You demonstrate your familiarity with the inspection process by mentioning specific components and NDT techniques.
?
3. How do you determine the appropriate pressure vessel inspection interval?
Answer: Determining inspection intervals involves taking into account factors such as the vessel's design, operating conditions, construction materials, corrosion rates, previous inspection findings, and applicable codes and standards. To determine inspection intervals, a risk-based approach that considers the probability and consequences of failure is commonly used.
Explanation: This question assesses your knowledge of the factors that influence inspection intervals and the significance of a risk-based approach. You demonstrate your ability to consider multiple factors in determining inspection frequencies by mentioning design, operating conditions, corrosion rates, and codes and standards.
?
4. What is hydrostatic testing, and when is it necessary?
Answer: Hydrostatic testing involves pressurising a pressure vessel with water or another suitable liquid to ensure its structural integrity. It is usually required for new vessels, after major repairs or alterations, or as part of the periodic revalidation process.
Explanation: This question tests your understanding of hydrostatic testing and its applications. You demonstrate a clear understanding of when and why hydrostatic testing is required by mentioning its purpose for new vessels, repairs, alterations, and revalidation.
?
5. What are the most common flaws or issues discovered during pressure vessel inspections?
Answer: Corrosion, erosion, cracking, distortion, inadequate welding, leakage, improperly functioning pressure relief devices, and insufficient insulation are some of the most common defects or issues encountered during pressure vessel inspections. The support structure, external coating, and corrosion under insulation issues may also be identified.
Explanation: This question assesses your knowledge of common pressure vessel inspection problems. You demonstrate a broad understanding of potential issues and concerns by mentioning corrosion, welding, pressure relief devices, and insulation defects.
?
6. How do you evaluate the integrity of pressure vessel welds?
Answer: Visual inspection, radiographic testing, ultrasonic testing, and other non-destructive testing methods are used to determine the integrity of pressure vessel welds. Visual inspection aids in the detection of surface defects, whereas radiographic and ultrasonic testing provide information about internal weld quality, including the detection of weld discontinuities.
Explanation: This question assesses your understanding of weld inspection techniques. You demonstrate your understanding of the various methods used to assess weld integrity by mentioning visual examination, radiographic testing, and ultrasonic testing.
?
7. What are the most important factors to consider when selecting appropriate pressure vessel repair methods?
Answer: When deciding on repair methods for pressure vessels, consider the nature and extent of the damage, the vessel's operating conditions, applicable codes and standards, and the qualifications of repair personnel. The chosen repair method must be capable of restoring the vessel's integrity and must comply with applicable regulations.

Explanation: This question tests your knowledge of the decision-making process for choosing repair methods. You demonstrate a comprehensive approach to selecting appropriate repair techniques by mentioning factors such as damage, operating conditions, codes and standards, and personnel qualifications.
?
8. How do you ensure that relevant codes and standards are followed during pressure vessel inspections?
Answer: It is critical to be familiar with the applicable codes, standards, and regulations, such as the ASME Boiler and Pressure Vessel Code, API standards, and jurisdictional requirements, in order to ensure compliance with codes and standards. Understanding the specific requirements of these standards, following recommended inspection practises, and staying up-to-date on any updates or amendments are all part of adhering to them.
Explanation: This question assesses your understanding of regulatory compliance as well as your ability to stay current on relevant codes and standards. You demonstrate your commitment to compliance by mentioning specific standards and emphasising the importance of continuous learning.
?
9. What paperwork is typically prepared as part of a pressure vessel inspection?
Answer: Inspection reports, NDT results, drawings, repair or alteration records, test certificates, and any other relevant documentation specific to the vessel's design, construction, and maintenance history are examples of documentation prepared during a pressure vessel inspection.
Explanation: This question assesses your knowledge of the documentation process used in pressure vessel inspections. You demonstrate your understanding of the comprehensive record-keeping required for inspections by mentioning various types of documents.
?
10. How do you effectively communicate inspection findings to stakeholders?
Answer: Effectively communicating inspection findings entails writing clear and concise reports outlining the scope of the inspection, identified defects or issues, their severity, recommended actions, and any compliance concerns. To facilitate understanding and decision-making by stakeholders, it is critical to use appropriate terminology and provide supporting evidence such as photographs or test results.
Explanation: This question assesses your ability to articulate and communicate inspection findings to the appropriate parties. You demonstrate your ability to communicate complex information accurately by mentioning key components of an inspection report and the importance of supporting evidence.
??
Remember to personalise your responses based on your experience and knowledge. Use the suggested answers as a starting point and modify them to reflect your own pressure vessel inspection expertise and understanding. Furthermore, conducting additional research and reviewing relevant codes and standards will help you prepare for your interview more thoroughly.
