Corrosion Protection of Flanges, Valves and Welded Joints - Application Experience

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, lab 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.
