OVERVIEW

Real-time UT Wall Thickness Monitoring Systems (RTUT) continuously monitor wall loss from corrosion or erosion by measuring absolute wall thickness in mm. This online NDT “installed ultrasound” technique facilitates continuous inspection of process pipework and vessels without the need for regular inspection manpower. The systems are EEx rated and non-intrusive, so they can be hooked up and maintained without any interruption to operations. The hardware is designed for both temporary and permanent applications, with both wired and wireless options available.

BENEFITS OF RTUT MONITORING

By identifying wall thinning areas before they become critical, RTUT solutions support the prevention of equipment failure and Loss of Primary Containment (LOPC). Data can be fully integrated with client control systems for HiHi alarming at Minimal Allowable Wall Thickness (MAWT). By preventing reactive repairs, RTUT can lower maintenance costs whilst enhancing reliability and operational efficiency.

APPLICATIONS OF RTUT MONITORING

• Pipeline corrosion and erosion monitoring – Detect wall thinning in critical flowlines without disrupting operations.
• Pressure vessels and separators – Monitor erosion-prone zones caused by turbulent flow and chemical exposure.
• Onshore plants and refineries – Continuously track corrosion in elbows, tees, and high-risk pipework sections.
• Remote and unmanned sites – Long-life wireless systems allow for hands-free data collection in inaccessible and isolated locations.
