Corrosion of flanges, valves and welded joints are major problems in the Oil & Gas, Chemical
Process, and other industries. This paper presents a summary of new cover designs, laboratory test
results, and application experiences in highly corrosive environments. This paper also describes the
efficiency and experiences of these new covers and systems using VCI protection in combination with
desiccants. In addition to offering corrosion protection, these covers have the added advantage of fast
installation and easy removal and cleanup. The results show that these covers provide increased
efficiency and service life for corrosion protection of various types of flanges, valves, welded joints in
outdoor and indoor environments.
