What is the PSIG range for Medium Pressure?

• A. 1 - 5 PSIG
• B. 2 - 15 PSIG
• C. 15 - 25 PSIG
• D. 10 - 12 PSIG

Answer: (B)

PSIG stands for pounds per square inch gauge, a pressure measurement relative to ambient atmospheric pressure. In gas distribution, pressures are grouped into Low, Medium, and High to match the equipment and regulators used. Medium pressure is defined as about 2 to 15 psig. This range provides enough pressure to deliver gas through distribution mains and to feed service regulators, while staying within the ratings of typical equipment and safety limits. The other ranges listed fall outside this standard band: 1–5 psig is generally considered too low for the medium-pressure category, 15–25 psig is typically associated with higher-pressure levels, and 10–12 psig is a narrow span not used as the standard category. So 2 to 15 psig is the correct range for Medium Pressure.
