Wi-Corr® CUI

Corrosion Under Insulation Prediction and Analytics

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.

Earliest possible detection

‘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.

Easy and non-intrusive installation

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.

Descriptive and actionable information

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.

Versatile solution for challenging environments

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.
