ST. PAUL, Minn. — Cortec® has developed VpCI®-337, a time-tested alternative to nitrogen blanketing for easy, effective corrosion protection of void spaces.
Nitrogen purge or nitrogen blanketing is commonly used to protect metal void spaces from corrosion by replacing the oxygen with nitrogen gas. However, there are three challenges to the success and efficiency of this method. First of all, nitrogen gas is expensive, raising a cost barrier especially where large spaces are concerned. The second challenge is that nitrogen requires constant pressure with an airtight seal. This necessitates regular monitoring and complete reapplication if a leak does occur. Third, leaks also pose a safety hazard for personnel who unknowingly enter an area where the deadly gas has settled and may be overcome in moments.
