CUI (Corrosion Under Insulation) is any type of corrosion that occurs due to water trapped under the insulation or fireproofing of pipes, pressure vessels or any other structure. CUI is a major industrial challenge with many industries dedicating 10% of their total annual maintenance budgets to repairing damage caused by CUI. At present, it is managed in many ways, ranging from full removal of insulation to the use of sophisticated and costly instrumentation.
We believe that insulated pipework should never fail due to external corrosion and that monitoring for CUI conditions to prevent failure should be affordable and effective.
Wi-Corr® CUI is the first wireless, retrofittable system capable of monitoring real-time for the conditions that cause corrosion under insulation. Wi-Corr® CUI integrates with the Trend Software and Data Platform and our proprietary algorithms to analyse the real-time data streamed from our easy-fit CUI sensors. Together they present clear, actionable information for a powerful new approach to addressing the huge cost of corrosion due to CUI.
‘Treat the cause – not the symptoms’
The Wi-Corr® CUI system is underpinned by patent-pending technology that turns an entire structure including its insulation into a sensing, coaxial cable-like structure. Radio waves injected into the insulation travel along the pipe up to 40 metres to detect corrosive environments. This enables a new systematic and data-driven approach to managing the corrosion as well as offering greater sensitivity to moisture build-up than established technologies.
Wi-Corr® CUI enables dramatic reductions in engineering costs through the earliest possible detection of the causes of CUI and through prompt identification of failing thermal insulation and associated energy inefficiencies.
The simple installation process offers rapid and flexible deployment of sensors with minimal disruption. Sensors are easily retrofitted within minutes to live pipes and vessels without the removal of cladding or insulation, requiring only a small hole in the cladding to insert the CUI sensor. IP66 leak-proof seals on all CUI hardware ensure installed equipment doesn’t produce a water ingress risk.
Once installed, sensors are powered autonomously with a 6+ year battery life under normal conditions. Batteries can be replaced easily at any time on a live plant. Devices can also be repositioned to a new location in minutes.
No permits required for operation and no hot-work permit is required for installation due to the Wi-Corr® range of pipe-safe installation tools. An excellent alternative to any application that might otherwise involve extensive permitting, engineering, cabling, and installation costs.
The integrated RBI (Risk Based Inspection) solution within Wi-Corr® Trend Software and Data Platform delivers accurate, descriptive diagnostics and visualisations. With actionable information and a clear interface, it can be used to help prioritise maintenance activity and assess maintenance performance, enabling better use of resources and reducing time in the field.
Compatible with widely used steel or aluminium cladding on all insulated structures inclusive of pipe bends, tees, steam tracers, tanks and vessels. Unlike other technologies, the Wi-Corr® CUI system is not just limited to non-ferromagnetic aluminium claddings and can be applied to the vast majority of clad structures in industry. Compatible with process temperatures up to 200ºC, giving full coverage of CUI threat temperatures.
Monitoring data is delivered over WirelessHART, the most secure, reliable, self-organising wireless network available. The industry recognised wireless technology is proven in cluttered industrial environments. The data is compatible with your existing DCS. Cellular and cloud networking can also be provided as an option if preferred.
A practical and efficient way of using field data to enhance the ‘Plan, Do, Check, Act’ (PDCA) process of mitigating unacceptable CUI risk in the most effective way, thereby improving plant safety and LOPC.
Rapid ROI is assisted by embedded descriptive, diagnostic and predictive analytics which deliver fast, actionable information.

Wi-Corr® UT is a revolutionary wireless monitoring system. Through a self- organising network of permanently installed, wireless enabled sensors, accurate pipe wall thickness and temperature can be obtained cost- effectively, enabling corrosion and erosion to be precisely monitored. This information allows a proactive approach in planning of turnarounds and preventative action
Corrosion and erosion-related failures of processing facilities are a major source of risk to upstream and downstream assets. Manual ultrasonic inspection of pipes gives poor reproducibility. Escalating costs are incurred by deploying inspection teams to facilities, obtaining work permits, preparing scaffolding, or in abseiling to access difficult locations.
In response to these challenges, Wi-Corr® UT has been developed to revolutionise the way asset integrity is assessed.

Wi-Corr® CUI is a revolutionary new monitoring system. Through a self-organizing network of permanently installed, wireless-enabled sensors, accurate measurements of moisture content of the thermal insulation over small or large distances can be obtained cost-effectively, so that the conditions that cause Corrosion Under Insulation (CUI) can be precisely monitored.
This information allows concentrations and movements of moisture in insulation to be tracked over great distances, enabling a proactive approach in planning of turnarounds and timely preventative action
The sensor data can remotely detect and predict corrosion development using advanced models and analytics. This can be incorporated into the existing asset management system of the asset owner.
