Preventing Corrosion During Hydrotesting

Hydrotesting of vessels, valves and pipelines, is carried out to ensure that no leaks are present and that the vessel will hold up under expected operating pressures, however it also raises the risk of corrosion by introducing moisture to the system. The same water that proves the vessel is not compromised can be the very cause of corrosion that deteriorates the metal and leads to leakage over time.

According to Cortec®, its VpCI®-649 inhibitor, a unique concentrated liquid formulation combining contact and Vapor phase Corrosion Inhibitors, can protect surfaces during hydrotesting. These inhibitors form a molecular protective layer on metal surfaces below and above the water level, and protect both ferrous and non-ferrous metals, including copper, steel, galvanized steel, aluminum, and cast iron. The inhibitor does not contain nitrites, phosphates, or chromates, which helps minimise disposal concerns, concluded the company.
