VpCI® Technology for Marine and Shipbuilding Industries
Corrosion is the undesirable material wear that appears by chemical action of the environment. It causes destruction of structures and equipment as well as loss of valuable resources, contamination of products, reduced efficiency and high maintenance costs. Damages from corrosion in shipbuilding or the ones that occur in the exploitation of various vessels are especially harsh. Corrosion protection of such structures and constructions make a big part of the cost of manufacturing process. Since all structural metals in certain circumstances are prone to corrosion, the economy is generating significant losses. In 2013, the direct cost of corrosion was 3.1% of the 15.1 Trillion U.S. GDP, which in June 2013 is estimated to equal to $500.7 Billion. If the indirect cost is also 3.1% of GDP, then the total cost of corrosion is $1001.4 Billion annually as of June 2013.
VpCI CORROSION INHIBITORS
The action mechanism of volatile corrosion inhibitor Inhibitors are used in various applications in shipbuilding, offshore and marine industry. Very often in structures that are present in these industries there are parts that are difficult to access or can even be completely inaccessible for quality and long-lasting protection against corrosion. In these cases the most efficient and economical technical solution is the use of VpCI® corrosion inhibitors. VpCI® corrosion inhibitors manufactured by Cortec® Corporation, world leader in innovative corrosion protection solutions are a special group of inhibitors that protect the metals from atmospheric corrosion and are able to stop corrosion at a molecular level. These organic substances vaporize and travel to all parts of the metal surfaces reaching even inaccessible areas. After contact with the metal surface, vapor condenses into air and forms a thin monomolecular film that protects the metal (Figure 1). Protective layer re-heals and self-replenishes through further condensation of the vapor. VpCI® reaches every area the metal part, protecting its exterior as well as hard-toreach interior surfaces. It provides complete product protection during storage as well as during domestic and overseas shipments.
BENEFITS OF VpCI® INHIBITORS IN SHIPBUILDING
The creation of mono- molecular inhibiting layer that protects even inaccessible areas; – If the VpCI® layer is disrupted mechanically or by opening the closed area, the layer is continuously replenished by evaporation
