Red Seal Steamfitter/Pipefitter Practice Exam

What is the main purpose of pressure testing in piping systems?

1. To clean the pipes

2. To check for leaks and ensure system integrity

3. To measure the temperature of the fluids

4. To install new piping

The correct answer is: To check for leaks and ensure system integrity

The main purpose of pressure testing in piping systems is to check for leaks and ensure system integrity. This testing procedure involves filling the piping system with water or air and then pressurizing it to a specific level. By doing so, any potential leaks or weak points in the system can be identified before the system is put into operation. This is crucial for safety and reliability, as leaks can lead to system failures, service interruptions, and environmental hazards. Moreover, pressure testing helps ascertain that the piping system can handle the operational pressures it will encounter during its intended use. It involves adhering to various codes and standards relevant to the specific application, which may dictate the required testing pressures and duration. Overall, this practice plays a critical role in maintaining the safety and efficiency of piping systems across various industries.
