What is the typical pressure range for non-pressure fixed facilities?

• A. 0-0.5 psig
• B. 25-500 psi
• C. 0-5 psig
• D. 10-20 psig

Answer: (A)

Non-pressure fixed facilities are designed to operate at essentially atmospheric pressure, with only tiny fluctuations. That means the pressure is around 0 psig, i.e., just above or equal to ambient, typically staying within a narrow window like 0 to 0.5 psig. The other ranges involve substantial pressure above ambient (tens of psi or more), which would classify the equipment as pressurized rather than non-pressure. So the 0 to 0.5 psig range best fits the description.
