What information is found on the exchanger nameplate?

• A. Exchanger model number
• B. Serial number
• C. Exchanger operating pressure
• D. Maximum temperature

Answer: (C)

Nameplates carry identification plus the safety limits you must operate within. The operating pressure listed on the plate is the value that defines what pressure the exchanger is designed to handle in service. It’s the critical constraint used to select compatible piping, valves, and safety devices, and to ensure you don’t exceed the vessel’s design capabilities. While model or serial numbers and sometimes maximum temperature may also be shown, the operating pressure is the information most directly tied to safe, correct operation, which is why it’s the best answer.
