What is medium gas pressure?
Medium pressure natural gas is considered to be a pressure over 14 inches of water column but not over 5 pounds per square inch gauge at the meter outlet. Medium pressure gas systems are sometimes desirable because of high gas demands and long lengths of piping between the gas meter and the equipment being served.
