Corrosion Under Insulation Screening Services

Corrosion under insulation (CUI) is expensive to manage because the corrosion usually cannot be identified without costly removal of the insulation then replacement of it afterwards. Not only is there the cost of removal and replacement of insulation, but also the facility downtime involved when that process is underway.  CUI is often discovered only after damage has occurred, leading to serious damages that cause equipment failure, safety hazards, reduced production and costly facility downtime.

Proactive CUI screening services not only help significantly reduce safety and production risks, but methods that enable screening without removal of insulation save significant costs and asset downtime.  

Intertek’s experienced CUI inspectors use a proven non-destructive testing method for real-time radiographic inspection of insulated piping. A combination of methods allows for efficient screening for anomalies in order to quickly identify where deeper attention is required, and where it is not. Identifying anomalies as small as 250 microns on insulated piping, this vital tool can screen hundreds of metres of insulated pipe within hours, enabling faster assessment and decisions.

Our unique anomaly detection technique can be applied while your facility is in operation and without the need of insulation removal, minimising disruption in your production and operating schedules.

Benefits include:

• Safety – eliminates work in confined spaces and hazardous environments
• Speed – instant inspection results
• Cost-Effectiveness – minimised asset downtime
• Minimal Preparation – no need to remove insulation, surface paint, coating or jacketing
• Portability – sites become highly accessible
• Visibility – high-resolution still images and videos

Intertek’s CUI screening can be combined with its other CUI management solutions such as moisture sensors and specific sizing techniques, as well as expert analysis and advice from Intertek CAPCIS, which has a global reputation as a leading authority in corrosion and materials assurance.
