XII International symposium on explosive production of new materials: science, technology, business and innovations(EPNM-2014) INDUSTRIAL-SCALE EXPLOSIVE WELDING OF CORROSION-RESISTANS MULTICLAD MATERIALS WITH “sacrificial pitting-protection” Prof.Andrey Rozen Cracow 2014
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).
