Static Equipment Interview Questions Verified Access

Used for storing fluids with high flash points or low volatility (e.g., diesel, heavy fuel oils, water). They present a risk of vapor emission and vacuum collapse if not properly vented.

Heat exchangers are the most complex static equipment due to thermal stresses and tube failures.

API 650/620 for atmospheric/low-pressure storage tanks, and ASME B31.3 for process piping. static equipment interview questions

How do you maintain a pressure vessel history folder? A: As per API 510 / ASME PCC-2, a folder should contain:

6. What is Post-Weld Heat Treatment (PWHT), and why is it required? Used for storing fluids with high flash points

When vapor velocity is too high, liquid droplets are carried upwards to the tray above instead of flowing down the downcomer. This destroys separation efficiency. It is the hydraulic limit of the tray.
