What is the PSIG range for High Pressure?

• A. 2 - 15 PSIG
• B. 15 - 125 PSIG
• C. 600 - 1400 PSIG
• D. 125 - 350 PSIG

Answer: (B)

Gas pressure in the distribution system is organized into bands so operators know which equipment and safety practices apply. The high-pressure band in this context is 15 to 125 PSIG. This range sits above the low-pressure regime, where regulation is more modest, and below the very high or transmission levels, which occur well above 125 PSIG (such as 600–1400 PSIG). So 15–125 PSIG best matches the typical high‑pressure portion of the distribution system, where regulators, meters, and related equipment are designed to operate reliably and safely. The other ranges fall outside this band: 2–15 PSIG is low pressure, 600–1400 PSIG is transmission/very high pressure, and 125–350 PSIG exceeds the defined high-pressure range in this context.
