Corrosion Monitoring
Non-Destructive Testing (NDT) using ultrasonic technology
The Ultramonit™ system uses ultrasonic pulse-echo technology to provide accurate measurements of internal corrosion and erosion rates.
Ultrasonic pulse-echo measurement is a well-established NDT (non-destructive testing)[1] method for measuring wall thickness and detecting defects. When it comes to corrosion monitoring, ultrasound has distinct advantages compared to other available technologies. It is non-invasive and measures the metal thickness directly and not via more or less dependable indicators.
Advances in low-noise electronics, sensor technology and signal processing algorithms now make it possible to achieve high resolution results using a permanently installed ultrasound unit.

The use of noninvasive techniques to determine the integrity of a material, component or structure or to quantitatively measure a characteristic of an object, i.e. inspect or measure without doing harm. Source: http://www.ndt-ed.org/index_flash.htm
Key advantages:
- Non-intrusive, meaning no threat to the integrity of the pipeline
- Number and placement of sensors determined according to client needs
- Predicts wall thickness reduction rate with very high accuracy
- Provides data to enable the prediction of the remaining lifetime of the pipeline
- Provides feedback on the effectiveness of corrosion inhibitors
- Efficient installation without interfering with the pipeline operation
- The equipment can be moved between different pipeline locations
- Data can be collected on line and in real time
- Data communication either wireless or via cable
- Direct access to results provided from any PC
- Delivers real time data
- Automated measurement, logging and analysis
- Flexible measurement intervals determined by client
- Can be installed subsea
- Can be installed on new pipelines or retrofitted to existing lines
