Corrosion is the degradation of material due to a chemical process and leads to the formation of sludge, erosion of metal surfaces and damage to equipment.
There are different types of corrosion: pitting, galvanic and uniform.
The causes may be very different.
For example: electrolysis, presence of foreign objects, water with unsuitable characteristics, presence of oxygen, CO2 formation, or H2, antifreeze products without corrosion inhibitors, temperature fluctuations during use, Iinadequate pump flow rates and operating pressures (cavitation).
