The problem of protecting equipment from corrosion while simultaneously ensuring elevated mechanical characteristics is acute in petroleum refining, and petrochemistry. Corrosion-resistant two-layer sheet steels have traditionally been widely used for manufacturing this equipment. Carbon or low-alloy steels selected as a function of the requirements for the mechanical properties of the articles are primarily the base layer of these steels. Corrosion-resistant steels of different brands, copper alloys (Monel, Inconel), nickel and nickel alloys, and titanium and its alloys are most widely used as the cladding layer which must be resistant to the aggressive effect of the environment.
