What is the maximum allowable operating pressure for gas systems as per ANSI standards?

The maximum allowable operating pressure for gas systems, according to ANSI standards, is indeed 5-PSIG. This standard is important for ensuring that gas systems operate safely and effectively. At this pressure, gas can flow through the system without risking leaks or failures that can occur at higher pressures.

When gas systems are designed and installed, adhering to this pressure limit is crucial for compliance with safety regulations and industry standards. This also ensures the reliability of the gas infrastructure, minimizing the risks associated with high-pressure systems, such as structural failures or unintended gas discharge.

Options indicating lower maximum pressures, such as 2-PSIG or 3-PSIG, do not meet the operational requirements for a wide range of gas applications, while 10-PSIG exceeds the safe thresholds established by ANSI. Therefore, understanding that 5-PSIG is the standard allows professionals to maintain safety and regulatory compliance in gas system installations and operations.
