While hydrotesting of industrial pipes and valves is done to ensure that no leaks are present, it also raises the risk of corrosion by introducing moisture to the system. Cortec’s VpCI-649 is a concentrated liquid formulation that combines contact and vapor-phase corrosion inhibitors to form a molecular protective layer on metal surfaces below and above the water level.
The liquid protects ferrous and nonferrous metals, including copper, steel, galvanized steel, aluminum, and cast iron. It does not contain nitrites, phosphates, or chromates and is available without molybdate.
The user decides how long they want corrosion protection to last and adjusts concentration and dwell time accordingly.
The Fabricator is North America's leading magazine for the metal forming and fabricating industry. The magazine delivers the news, technical articles, and case histories that enable fabricators to do their jobs more efficiently. The Fabricator has served the industry since 1970.
