Protection of Equipment for Storage and Transport with Vapor Phase Corrosion Inhibitors

Application of Vapor phase Corrosion Inhibitors (VCI) for protection of various industrial and military equipment from corrosion during storage and overseas transport provides numerous advantages. When VCI inhibitors are being applied during the process of corrosion protection they will enable strong protection of the equipment during storage and transport without additional time and money needed prior to putting equipment in operation. During transport the equipment travels through various climate zones experiencing changes in temperature and humidity that are favorable to corrosion. Changes in humidity and temperature levels during transport even at very short distances can create moisture that condenses into water. Properly chosen combination of Vapor phase corrosion inhibitors enables the equipment and its components (especially electrical components) to resist the corrosion caused by moisture and aggressive saline environment. The requirements that need to be fulfilled during the application of inhibitors vary depending on the conditions of the application as well as required time limits of corrosion protection process. Vapor phase Corrosion Inhibitors (VCI's) are thermo-stable and they do not damage ferrous or non-ferrous metals. Inhibitors will not affect electrical, physical or chemical properties of lubricants if used in lubrication systems. The paper includes laboratory testing data and application methods of shrink film, impregnated foams and coatings containing vapor corrosion inhibitor (VCI) that are being applied in conservation process of industrial and military equipment. The experimental part of this paper will include validation of effectiveness of this system using standard test methods according to ASTM, MIL-SPEC, NACE and DIN standards.
