Corrosion inhibiting vapor for use in connection with encased articles

摘要

A volatile corrosion inhibiting agent is provided for dispersion of a vapor phase corrosion inhibitor in a vapor stream that is passed into a sheath or other casing enclosing a metal bar, cable, or other tension member to protect said tension member from corrosion.

主权项

1. A corrosion inhibition system, including:
an elongate metal tension member, a cover disposed in surrounding relation to the tension member and cooperating with the tension member to define an interior volume between the tension member and the cover, a vapor stream comprising a carrier gas motivated in a proximity to a volatile corrosion inhibiting agent composition to cause dispersal within said carrier gas of a vapor phase corrosion inhibitor, said vapor stream being motivated into said interior volume, and said volatile corrosion inhibiting agent composition comprising at least a first fast volatile corrosion inhibitor and a second slow volatile corrosion inhibitor.
