Red Seal Steamfitter/Pipefitter Practice Exam

What is the primary purpose of a pressure gauge in a piping system?

1. To increase fluid flow

2. To control valve openings

3. To measure fluid temperature

4. To measure the internal pressure of a fluid

The correct answer is: To measure the internal pressure of a fluid

The primary purpose of a pressure gauge in a piping system is to measure the internal pressure of a fluid. This function is crucial for monitoring system performance, ensuring safety, and maintaining operational efficiency. By providing real-time pressure readings, the gauge allows for the identification of potential issues such as overpressure, which can lead to failures, leaks, or safety hazards. Proper monitoring also helps in the control and optimization of fluid flow and system maintenance, as pressure levels can influence the overall behavior of the system. Measuring temperature, controlling valve openings, and increasing fluid flow are not the direct or primary functions of a pressure gauge. While these elements can be influenced by or have relationships with the pressure measured, they do not pertain directly to the gauge’s fundamental role. The importance of accurately gauging pressure cannot be overstated, as it forms the basis for effective system management in any steamfitter or pipefitter application.
