Passivation and Preservation
Especially, after chemical cleaning, HP water jetting or hydrostatic pressure testing, it is important to dry the system and to ensure the prevention of contamination and oxidation (corrosion). If the system cannot be put into operation immediately, or if the pre-cleaned pipes and components have to be stored for an indefinite period, Ocean Team can passivate and preserve the system using various technologies depending on the application.
In some applications, it is beneficial to pressurize the system with nitrogen (careful monitoring is however necessary). In other applications, Ocean Team have had great success with Vapour Corrosion Inhibitors (VCIs), which also provide metal surfaces with excellent protection, preventing corrosion for many years.
VCIs are chemicals that are applied directly to the product needing protection. They are designed to create an invisible barrier, keeping moisture at bay. VCI molecules attach themselves to the metal surface, forming a thin, invisible film only a few molecules thick.
Let Ocean Team help you choose the best preservation and passivation method to meet your demands.
