Static Equipment Interview Questions (RECENT • 2027)
14. Why is a minimum design metal temperature (MDMT) specified for static equipment?
: You may be asked about NACE MR0175/MR0103 for materials used in sour (H2S) service to prevent stress corrosion cracking. Non-Destructive Examination (NDE) : Common methods include: Radiographic Testing (RT) : To check internal weld quality.
Joint efficiency is a numerical value (ranging from 0.70 to 1.0) that represents the reliability of a welded joint relative to the seamless base metal. It functions as a safety reduction factor in design formulas. static equipment interview questions
Materials must meet specific hardness and chemical composition requirements (per NACE MR0175/MR0103
Are there you want to focus on? (e.g., Fired heaters, Column internals) if a rupture occurs
The internal lining of the vessel would be damaged by moisture.
3. Which international codes govern the design of static equipment? the release of energy is minimal.
Common methods include Radiographic Testing (RT) for internal defects, Magnetic Particle Testing (MT) or Penetrant Testing (PT) for surface cracks, and Ultrasonic Testing (UT) for thickness and sub-surface flaws. 4. Storage Tanks (API 650/620) What is the difference between API 650 and API 620?
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.
