Petrofac Interview Questions, Process, and Tips

Stress critical line list is prepared by identifying lines that are critical for the safe operation of the plant.

• Identify lines that carry hazardous fluids or operate at high temperatures/pressures

• Determine the consequences of failure for each line

• Consider the location of the line and its accessibility for maintenance

• Prioritize the lines based on their criticality and assign appropriate stress limits

• Update the list reg...read more

Flange leakage can be detected by visual inspection, pressure testing, or using ultrasonic or acoustic emission techniques.

• Visual inspection involves checking for signs of leakage such as stains or discoloration around the flange.

• Pressure testing involves pressurizing the system and checking for any drop in pressure over time.

• Ultrasonic or acoustic emission techniques involve using sensors to detect any sound or vibrat...read more
