When answering questions, adopt a mindset of safety and reliability. If you don't know a specific answer, explain your logic. For example, if asked about a specific material property, discuss how you would look it up in the ASME Section II tables. This shows resourcefulness—a trait highly valued in engineering. By mastering the interplay between design codes and degradation mechanisms, you will position yourself as a competent and reliable engineer.

Reference API 510. You would calculate the remaining life using the formula involving design pressure, current thickness, and corrosion rate. You might also mention "Fitness-For-Service" (API 579), which allows engineers to determine if a flaw is acceptable to remain in service or if it requires repair, rather than simply condemning the equipment.
Uses water as the testing medium. The vessel is typically pressurized to 1.3 times the Maximum Allowable Working Pressure (MAWP). It is inherently safer because water is virtually incompressible; if a rupture occurs, the release of energy is minimal.
For senior engineers or designers.
Be very familiar with ASME Section VIII Div 1, API 510, and API 650 [1].
