    24/6/2014 · 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. 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.

    4/5/2016 · Boiler pH should be kept between 10.5 and 12.5. Below 10.5, there is insufficient protection from corrosion and hardness compounds are not precipitated in the desired, free-flowing form. Above 12.5 there is the possibility of caustic embrittlement and carryover. Condensate pH should be kept between 8.0 and 8.6.

    Boiler water pH refers to a quantitative figure that expresses the acidity or alkalinity of boiler water. Ideally it should be between 8.5 and 9.5. If the pH is lower than that, the boiler water will start eating the pipes and attacks the boiler equipments as well.

    When calcium phosphate is formed in boiler water of sufficient alkalinity (pH 11.0-12.0), a particle with a relatively nonadherent surface charge is produced. This does not prevent the development of deposit accumulations over time, but the deposits can be controlled reasonably well by blowdown.
