Reason 1: Chemical corrosion of water on pipelines
The main chemical component of pipelines is iron, due to the high reactivity of iron Because of hydrogen, the pipeline undergoes the following oxidation reaction with oxygen in the air after contacting water:
+rr
It is rust, and the pipeline has been corroded at this time.
Therefore, before laying pipelines, the pipelines are coated with anti-corrosion paint to minimize the above-mentioned chemical corrosion.
Reason 2: Chemical corrosion of pipelines by electric current
As fluid flows in pipelines, friction will generate static electricity. At the same time, the earth and space also contain charges, and iron, the main component of pipelines, is a good conductor. As mentioned above Static electricity will create a voltage in local pipelines. This voltage is enough to ionize iron to form iron ions (+++).
