Static Equipment Interview Questions |work| Jun 2026

Piping components are categorized into standard Pressure-Temperature ratings or "Classes" (e.g., Class 150, 300, 600, 900, 1500, 2500) according to . The class number does not represent a static psi rating.

Static equipment fails due to materials science issues, not just over-pressure.

Explain the TEMA designations for shell and tube heat exchangers. static equipment interview questions

: Can you explain flange design according to ASME Section VIII, Div 1, Appendix 2 ?

According to ASME Section VIII Division 1 (UG-99), the standard hydrostatic test pressure must be at least the MAWP, multiplied by a temperature correction factor (the ratio of allowable stress at test temperature to allowable stress at design temperature).The test serves three primary purposes: Explain the TEMA designations for shell and tube

Affects carbon steels when exposed to high concentrations of caustic soda (NaOH) at elevated temperatures. 5. Piping, Flanges, and Piping Components (ASME B31.3)

Radiography (RT) / Ultrasonic (UT): Internal/volumetric flaws. not just over-pressure.

: How do you apply Risk-Based Inspection (RBI) principles or predictive maintenance to stationary equipment like tanks and columns? Behavioral & Situation-Based Questions

Remind readers that it’s not just about memorizing codes; it’s about understanding safety and risk management .

Fixed tubesheets are cheaper but cannot handle high thermal expansion, suitable for smaller temperature differences. U-Tube exchangers are ideal for high thermal expansion because the tube bundle can expand freely.
