EcoLine® VpCI®-642 Offshore Hydrotesting Inhibitor

Product Description

EcoLine® VpCI®-642 is an economical inhibitor specially designed for hydrotesting with sea water. It effectively protects ferrous metals from corrosive, high-chloride environments by forming a protective layer on metal surface and by inhibiting cathodic corrosion reactions. EcoLine® VpCI®-642 has been certified as 93% Biobased by the USDA.

For offshore oil and gas pipelines, the ability to utilize abundant sea water provides tremendous cost savings. However, untreated sea water poses serious risks of equipment corrosion. With the addition of EcoLine® VpCI®-642, sea water can be safely utilized without the danger of premature corrosive equipment failure.

EcoLine® VpCI®-642 is effective as a replacement for nitrite, chromate, and hydrazine-based rust preventative products. With the environmentally friendly profile of EcoLine® VpCI®-642, disposal of large quantities of used hydrotesting water is more likely to comply with local regulations.

Not limited to hydrotesting applications, EcoLine® VpCI®-642 offers a low dosage treatment for a wide variety of process applications employing salt water.
