Jun 24, 2014 · And even if you fix the leaks in the system, you still have to keep an eye on the pH of the water because many people add chemicals to their boilers to avoid corrosion. These chemicals shove the pH toward the alkaline side of the scale. When the pH reaches 10, corrosion becomes impossible. That's what makes chemical drain cleaners safe for pipes.Get Price
A typically recommended alkalinity rating is 140 – 700 ppm for boilers operating below 300 psi. Controlling pH pH is controlled by either removing water impurities or adding other chemicals to neutralize the condition. For example, Caustic Soda, an alkaline, is added to neutralize CO3, carbonic acid. pH Related Corrosion Acid AttackGet Price
