ZERUST® ZerioGuard™ 12
ZERUST® ZerioGuard™ 12 is a high-performance corrosion-inhibiting formulation specifically designed for hydrostatic testing and post-testing lay-up. This versatile solution is engineered to provide reliable, long-lasting protection for assets of various sizes and geometries.
ZERUST® ZerioGuard™ 12 combines Soluble Corrosion Inhibitors (SCIs) and Vapor Corrosion Inhibitors (VCIs) to deliver comprehensive corrosion protection. SCIs protect metal surfaces in direct contact with the solution, making them ideal for fully filled assets during hydrostatic testing. VCIs, on the other hand, diffuse into airspaces within the asset, saturating these areas to safeguard against corrosion that may not be in direct contact with the solution.
With its advanced formulation, ZERUST® ZerioGuard™ 12 simplifies application while delivering exceptional corrosion resistance and durability, effectively mitigating corrosion risks during hydrostatic testing and subsequent storage.
Typical Applications
- Hydrotesting of pipelines, piping systems and vessels
- Wet layup
Key Advantages
- Effective at low concentrations
- Neutralizes contaminants and corrosive species in the hydrotest water
- System remains protected after draining of water due to VCI protection
Operating Summary
- Mix ZERUST® ZerioGuard™ 12 thoroughly into water until fully dissolved. Concentration depends on length of time the asset will be in contact with the solution, condition of the asset, and quality of the water.*
- Apply solution to asset as specified in the Scope of Work. A ZERUST® Field Engineer can be assigned to oversee the operation.
- Dispose of the solution in accordance with local, regional, national, and international regulations as applicable.
