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. If its higher than that, the water wont corrode metal, but it may begin to foam, and thats not good. Hold that thought for a moment.

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
Dec 15, 2019 · An alkaline boil-out, normally used to remove contaminants, removes the protective coatings applied during construction, plus any oil or grease that accumulated during erection, installation, or repair. The boil-out should be a type that provides the greatest detergent, emulsifying, and dispersing action possible.
Feb 16, 2017 · I answered "NO" because the typical commercial-espresso machine's steam-boiler water is alkaline and packed with minerals. When used to brew tea or coffee it results in a chalky taste. When added to an already-brewed espresso to make a drink such as an americano or long black, the effect is less pronounced, but the steam-boiler water is still usually not the best choice.
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.
