What is the pressure threshold that qualifies as a high-pressure line of natural gas?

In the context of natural gas systems, a pressure threshold that designates a high-pressure line is crucial for safety and regulatory compliance. A line is considered to be high pressure when it exceeds 2 PSIG (pounds per square inch gauge). This classification has implications for the design, maintenance, and monitoring of natural gas infrastructure.

Lines operating at or below 2 PSIG fall into the category of low-pressure lines, which are subject to different regulations and safety requirements compared to high-pressure lines. High-pressure systems may involve more robust materials, more stringent safety measures, and a higher level of monitoring to prevent leaks and ensure safe operation.

Understanding this classification helps technicians and engineers work safely with natural gas systems, ensuring compliance with industry standards and regulations while minimizing risks associated with high-pressure gas lines.
