The importance of pH in steam-boiler water

If the pH is lower than that, the water will start eating the pipes. If it's higher than that, the water won't corrode metal, but it may begin to foam, and that's not good. Hold that thought for a moment. You're on a job and you have a steam boiler that's taking on a lot of feed water because the system has leaks.

Basic Steam Theory - Steam Pressure

Now the steam coming out of the kitchen kettle (and out of the imaginary spout on our boiler) is exposed to atmosphere and is therefore at Atmospheric Pressure of 101.3 kPa. The temperature of steam at this atmospheric pressure is the same as the temperature of boiling water at atmosperic pressure, which is 100 deg.C.
