Jun 24, 2014 · It comes into play with steam boilers because a pH between 7 and 9 (slightly alkaline) is just right. If the pH is lower than that, the water will start eating the pipes.

3.2.1 Oxygen in the presence of water cooler than 212°F can cause a serious destructive activity called oxygen corrosion. The amount of oxygen absorbed in water is proportional to temperature and pressure. See examples below: 70° F water at 0 psig contains approximately 8.6 ppm; 150° F water at 0 psig contains approximately 4.3 ppm; and

Condensate Water Treatment to Prevent Steam Boiler Pipes

Alkalinity Relationships. In boiler water, treatment specialists must maintain M (or T) alkalinity below a maximum level prescribed by the boiler's manufacturer to help prevent foaming and carryover. Typically, as boiler operating pressure increases so does the need for higher purity water.
