Definition: The area of a flow curve under which flow demand is greater than the pressure-controlling capabilities of the regulator. Dead-head regulators can also cause "creep" which means the fuel pressure tends to slowly increase.

When a regulator is brand new it needs to get worn in, this is what we call the imbedding period of the regulator. It is a generally slow developing form of degradation occurring in metals under stress and higher pressures. Using a regulator with a soft seat can reduce the opportunity for creep. The regulator pressure creeping up from the adjusted regulator pressure, for instance, you adjust the regulator to 150 bar, and over time, it creeps up to let’s say, 170 bar. The amount of creep deformation that will be experienced is highly dependent upon the level of stress, level of temperature, and material properties of the metal. 31 - Describe the difference between an argon cylinder...
