Pitting - Corrosion
| ||In metal pipes which are subject to corrosion, it can be anticipated that the pipes will leak after a certain time. This is referred to as "pitting" even though this is not actually entirely correct. Viewed classically, pitting occurs on metals as the result of a galvanic element. This is produced if two different metals, e.g. copper and iron, come together. This results in a voltage, like on a battery. The pipe is getting weaker at this spot and slowly a hole will be build from inside. Finally the pipe starts to leak. Consequently, a section of brass must always be fitted in the case of mixed piping between the copper pipes and the iron pipes in order to prevent direct contact in between two materials and avoid the galvanic corrosion.|
Of course Pursanova TM is not always able to prevent pitting as the result of differing elements since strong chemical forces act in such cases. Consequently, in private homes or when possible in the industry, it is always advisable to install a particle filter at the branch line to the building in order to prevent a different metal being entrained from the outside.
There are other reasons for pitting as well, such as high velocity or pitting from outside the pipe. These Pursanova TM has of course no effect on.
