Corrosion Protection During Hydrotesting from Cortec
Cortec® provides the VpCI®-649 Series for the hydrotesting of industrial pipes, valves, and other vessels. VpCI-649 is a concentrated liquid formulation that combines contact and vapor phase corrosion inhibitors. These inhibitors form a molecular protective layer on metal surfaces below and above the water level. VpCI-649 protects both ferrous and non-ferrous metals, including copper, steel, galvanized steel, aluminum, and cast iron. VpCI-649 does not contain nitrites, phosphates, or chromates—a characteristic that helps minimize disposal concerns. It is also available in a molybdate-free version (VpCI-649 MF) for use in regions with molybdate restrictions. VpCI-649 BD contains an organic-dispersing agent, and VpCI-649 Winterized provides protection against product-freezing during storage.
