What temperature corresponds to 200 psig in steam systems?

In steam systems, the pressure of the steam is directly related to its saturation temperature, which is the temperature at which water converts to steam. For 200 psig (pounds per square inch gauge), the temperature that corresponds to this pressure can be determined using steam tables or steam pressure-temperature charts.

At 200 psig, the corresponding saturation temperature is approximately 413°F. This value is crucial for operators to understand as it indicates the temperature at which steam can exist at this pressure without condensing back into water. Knowing the saturation temperature ensures that the steam systems operate efficiently and safely, as exceeding this temperature at that pressure could lead to overpressure situations and potential hazards.

Therefore, the correct answer, which corresponds to the saturation point for steam at 200 psig, is 413°F. This aligns with the principles of thermodynamics and the behavior of water and steam in high-pressure boiler systems.
