Layup Protection with Vapor Phase Corrosion Inhibitors (VPCI)
Instructor: Scott Bryan, Technical Sales Manager, Cortec Corporation
Long-term layup of steam generators, cooling water systems and other water networks exposes water-touched metal to serious corrosion, especially from in-leakage of air at potentially numerous points in the system. Often, these systems must remain water-filled for rapid startup when needed. VPCIs have become a mature technology for protecting metals in many applications.
This presentation explains how VPCIs function, where they perform best and how they can complement or replace traditional layup practices. Attendees will review application techniques for both wet and dry systems, considerations for water-filled standby conditions and verification methods to confirm protection effectiveness. Real-world examples will illustrate how utilities and industrial plants are using VPCIs to safeguard assets and enable faster, corrosion-free restarts.
