PRESS RELEASE: Exciting Breakthrough! New Corrosion Inhibitor for Hydrotesting Drinking Water Systems

Cortec® is pleased to announce that its newest corrosion inhibitor for hydrostatic testing (i.e., hydrotesting) is certified to meet ANSI/NSF Standard 61 for use in hydrotesting of drinking water system components!This opens exciting opportunities for those who fabricate, install, or service drinking water system components held to stringent safety requirements.

How VpCI®-649 HP Works
VpCI®-649 HP is a specialty concentrated liquid formulation that contains contact and Vapor phase Corrosion Inhibitors, along with a hard water stabilizer and an organic dispersing agent. It protects against corrosion at dosages as low as 0.3% by weight. It also has an extremely low chloride impact (less than 0.6 ppm at 0.3% dosage) for use in systems with tight chloride restrictions. As VpCI®-649 HP circulates throughout the system, it leaves behind a protective molecular layer on all metal surfaces. After the water treated with VpCI®-649 HP has been drained, residual protection continues on components made of steel, copper, galvanized steel, or aluminum.

Hydrotesting Drinking Water System Components
VpCI®-649 HP is primarily intended for corrosion protection during hydrotesting. This is a critical practice used in many industries to ensure vessels, piping, and tanks do not leak and can withstand pressure specifications. The unfortunate side effect is that moisture can incite corrosion during and after hydrotesting, leading to further problems during the lifetime of the new components.

In the past, many industries have found standard VpCI®-649 to be an outstanding source of corrosion protection during this sensitive phase. Use, however, was limited to equipment that would not be exposed to drinking water. With the development of VpCI®-649 HP and its certification to meet ANSI/NSF Standard 61 for use in treatment of drinking water system components, the opportunities for corrosion protection during hydrotesting of pumps, valves, piping, fittings, and tanks used to carry potable water have suddenly expanded!

Beyond Hydrotesting
The safety of VpCI®-649 HP for treating components that will be used with drinking water systems also carries implications for use in the dry layup of closed loops and cooling water systems in the food and beverage industry. VpCI®-649 HP can be added to either fresh water or glycol coolants, circulated, and drained for equipment preservation. Dry layup of fire extinguishing systems with VpCI®-649 HP as an alternative to nitrogen purge and/or compressed air is another option.

Take Advantage of This Exciting Breakthrough!
VpCI®-649 HP is an exciting breakthrough for Cortec® and users alike. With VpCI®-649 HP, users have the freedom to effectively protect drinking water system components and other regulated systems from corrosion during hydrotesting and layup.
