Actuality
Annual global financial
losses from corrosion are
estimated as $2.2 trillion,
which appears to be from
2.0 to 6.0% of national
GNPs. In particular, last
year the losses totaled:
- $442 billion in the USA,
- $94 billion in Germany,
- $51 billion in Russia.
An element of the pipe transporting
halogens containing liquids (F, Cl, Br, I).
