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).
