What is the PSIG range for Interstate Pipelines?

• A. 125 - 350 PSIG
• B. 1 - 5 PSIG
• C. 15 - 125 PSIG
• D. 600 - 1400 PSIG

Answer: (D)

Interstate pipelines operate as high‑pressure transmission lines that move gas long distances. To push gas efficiently through long routes and overcome friction losses, these systems run at high gauge pressures, typically in the 600 to 1400 PSIG range. PSIG means pressure measured relative to atmospheric pressure, which is how transmission pressures are specified. This high pressure sets apart interstate transmission from distribution and service lines, which operate at much lower pressures—often in the single digits to a few dozen psi or up to about 125 psi in some cases. So the standard operating range for interstate transmission is 600–1400 PSIG.
