Cortec’s VpCI® technology creates a self-replenishing molecular layer that actively bonds to metal surfaces, completely eliminating the need for labour-intensive degreasing and cleaning once the turbine is ready for deployment.
Managing the corrosion of high-value industrial assets during transport and long-term storage remains a significant financial headache for manufacturers and power companies worldwide. To address this challenge, Cortec® Corporation has detailed how its advanced Vapor phase Corrosion Inhibitors (VpCI®) deliver efficient, cost-effective corrosion protection for critical steam, gas, and wind turbines.
Turbines frequently travel thousands of miles across harsh maritime or tropical climates, or sit awaiting commissioning at new facilities. Traditional preservation methods, such as tarpaulins or complex pressurised nitrogen systems, can be unreliable or operationally cumbersome. In contrast, VpCI® technology creates a self-replenishing molecular layer
that actively bonds to metal surfaces, completely eliminating the need for labour-intensive degreasing and cleaning once the turbine is ready for deployment.
Effective turbine preservation relies on a combination of internal and external corrosion protection:
- External Shelling: Heavy-duty materials like VpCI®-126 HP UV Shrink Film or MilCorr® VpCI® Shrink Film form an impenetrable barrier against wind, rain, and aggressive salt environments while keeping the protective vapours contained.
- Internal Emitters: To protect complex internal flow paths, engineers deploy specialized internal emitters, such as VpCI®-308 Pouches or CorroLogic® Fogging Fluid VpCI®-339, ensuring complete coverage of enclosed spaces.
Cortec’s corrosion protection methods have already been successfully deployed across several high-stakes international projects:
- United Kingdom: Three multi-million-pound power plant turbines that had begun rusting under basic tarpaulins were successfully stabilised and preserved outdoors for several years using VpCI®-132 Foam and VpCI®-126 HP UV Shrink Film.
- Kazakhstan: A gas turbine engine was outfitted with internal EcoPouches and shrink-wrapped for a gruelling, month-long 5,000-mile road transit.
- Indonesia: Five steam-turbine generator sets were kept pristine throughout a two-year pre-commissioning delay at a refinery, relying on MilCorr® film and Desicorr® VpCI® Pouches to withstand extreme tropical weather.
