Innovating industrial preservation: Cortec’s new vapour-phase fogging fluid offers a practical, high-performance alternative to traditional purge methods.
A significant shift is occurring within the manufacturing and energy sectors as industry leaders move away from traditional coatings and nitrogen purging for the protection of internal voids. With the introduction of CorroLogic® Fogging Fluid VpCI®-339, fabricators are finding a more robust and efficient solution for preserving complex equipment.
The challenges of preventing corrosion in intricate structural and equipment voids, such as heat exchangers, pipeline segments, and oil and gas modules, have long been a source of operational strain. Historically, nitrogen purging was the standard, despite being costly and requiring a continuous, airtight seal. Should that seal be compromised, the entire preservation process would have to be repeated.
Cortec’s new vapour-phase corrosion inhibitor (VpCI®) technology is now being favoured for its "fog and forget" simplicity. The fluid relies on vapour-phase action to diffuse throughout a void, creating a protective molecular layer on both ferrous and non-ferrous metals, including carbon steel, stainless steel, cast iron, aluminium, and copper.
Beyond ease of application, the fluid is soluble in both water and hydrocarbons, which significantly reduces the need for extensive flushing prior to commissioning. As the industry seeks to standardise more effective, low-maintenance preservation protocols for transport, temporary layups, and long-term storage, this technology is rapidly gaining traction as the preferred alternative to traditional methods.
