Plant Operation Test 2025 – 400 Free Practice Questions to Pass the Exam

The typical pressure range for a natural gas distribution system is generally found to be between 1 to 60 psi. This range is designed to ensure that natural gas can be delivered safely and efficiently to residential and commercial consumers while maintaining a level that prevents over-pressurization and associated hazards. This pressure level strikes a balance between the necessity of delivering gas effectively and the safety requirements mandated by regulations.

Options that suggest significantly lower or higher pressure ranges do not accurately reflect the operational pressures necessary for standard gas distribution systems. For instance, pressures below 1 psi may not be sufficient for reliable gas flow, while pressures exceeding 60 psi typically indicate a different classification of service, which could pertain to larger industrial applications or transmission pipelines rather than standard distribution. Therefore, the range of 1 to 60 psi is the most appropriate for typical natural gas distribution systems.
