Abstract: The importance of corrosion protection in industrialized regions, providing industrial security of enterprises is considered. The technical analysis of metal and concrete structures of industrial enterprises operating in contact with the industrial environment of Kuzbass region, shows that the corrosion attack begins six months after their commissioning. Corrosive components of industrial environment (aggressive dust particles, carbon oxide and dioxide, sulfur compounds, chlorine, nitrogen oxides, etc.) are adsorbed onto the concrete and metal surface, always having a multimolecular layer of water, and being dissolved in the latter form electrolytes promoting intensive development of corrosion processes in the cement stone and metal according to the electrochemical mechanism. This process leads to irreversible corrosion damage. As a result, the actual terms of operational reliability of the objects do not meet regulatory requirements and do not provide the required level of industrial safety of the enterprise. The analysis of the technical conditions of metal and concrete structures of industrial enterprises is made; the corrosive components of the industrial environment are valued. The optimal solutions for corrosion protection without the renovation of protected surfaces are offered and proved.
