What does Set Pressure refer to in a gas system?

Set Pressure specifically refers to the predetermined pressure level at which a relief valve will open to release excess pressure in a gas system. This is a critical safety feature designed to protect the system from being exposed to pressures that may exceed the structural capabilities of its components, which could lead to failures or hazardous situations.

Understanding the role of set pressure is vital for safe operations, particularly in systems utilizing fuels like compressed natural gas (CNG), where maintaining appropriate pressure levels is crucial for both performance and safety. By ensuring that relief valves open at the set pressure, the system is protected from potential over-pressurization, thereby minimizing the risk of accidents or equipment failure.

The other potential meanings of pressure in various contexts do not align with the definition of set pressure in relation to safety valves, as they pertain to different aspects of gas system operations.
