SELECTIVE LEACHING CORROSION S031
The process fluid selectively removes elements from the piping or any other component that might be exposed to the liquid flow. The mechanism is as follows:
- Metals are removed from the liquid during a de-ionization or de-mineralizing process.
- The liquid tries to replace the missing elements as it flows through the system.
- The un-dissolved metals often coat themselves on the mechanical seal faces or the sliding components and cause a premature seal failure.
- Heat accelerates the process.
