Sample interview questions: Can you explain the process of pressure testing and balancing pipe systems?
Sample answer:
- Pressure Testing:
- Isolating the system by closing valves.
- Attaching a pressure gauge to a test port.
- Gradually pressurizing the system, using a hand pump or a compressed air source.
- Observing the pressure gauge for any sudden drops or leaks.
-
Slowly releasing the pressure.
-
Balancing Pipe Systems:
- Measuring the flow rate at various points in the system using a flow meter.
- Adjusting valves to achieve a desired flow rate.
-
Using balancing valves or balancing loops to fine-tune the flow.
-
Tips for Success:
- Ensure all valves are fully closed/open before starting the pressure test.
- Gradually pressurize the system to avoid sudden pre… Read full answer
