What items must be checked prior to conducting a pressure test to avoid damage?

• A. Control valves and check valves.
• B. Gage glasses, expansion joints, instrumentation, and pressure relief valves.
• C. Thermometers and flow meters.
• D. Seals and bearings.

Answer: (B)

Prior to conducting a pressure test, it is crucial to check specific components within the system to ensure they can withstand the applied pressure without risking damage or failure. Selecting instrumentation and other elements like gage glasses, expansion joints, and pressure relief valves for inspection is paramount because these components are integral to the safe operation and monitoring of the piping system during a test. Gage glasses and instrumentation are typically designed to measure the pressure of the system; if they are not functioning correctly, it could lead to incorrect readings that may cause the operator to apply excessive pressure. Expansion joints must also be assessed, as they accommodate movement and thermal expansion; any defects or compromises in these joints could result in significant failures under pressure. Pressure relief valves are critical safety components that must be operational to prevent overpressurization, which can lead to catastrophic failures. In contrast, while control valves and check valves, thermometers, flow meters, and seals and bearings are important parts of the piping system, they are less critical to inspect immediately before a pressure test in terms of preventing potential damage during the test. Their failure, while serious, might not directly lead to the same immediate risks during the pressure testing process as the ones listed in the correct choice. Thus, focusing on those specific components
