G2 Gas Fitter Practice Exam

Question: 1 / 400

What is the primary purpose of a relief device in a piping system?

To increase gas pressure during normal operations

To prevent a rise of gas pressure due to emergency conditions

The primary purpose of a relief device in a piping system is to prevent a rise of gas pressure due to emergency conditions. Relief devices, such as pressure relief valves, are crucial safety components designed to protect piping systems from overpressure situations that can occur during unforeseen circumstances like equipment failures or thermal expansion. When the pressure in the system exceeds a predetermined limit, the relief device activates to release excess pressure, preventing potential hazards such as pipe bursts, leaks, or catastrophic failures.

This role is essential in maintaining the integrity and safety of the system, ensuring that it operates within the safe pressure limits specified by regulatory standards and engineering best practices. Relief devices are not designed to increase pressure, allow unrestricted escape of gas, or enhance flow rates; instead, their focus is on pressure regulation and safety.
