Corrosion

Corrosion occurs when the parent metal oxidises (as iron rusts, for example) and gradually the integrity of the plant equipment is compromised. The corrosion products can cause similar problems to scale, but corrosion can also lead to leaks, which in a pressurised system can lead to catastrophic failures.

Corrosion damage in closed heating and cooling water systems is a common problem. These systems are found in commercial, industrial and residential buildings as an integral part of the heating, ventilation and air conditioning system.
