Rightrax LT (Low Temp) system

Corrosion and erosion monitoring using permanently installed technology for continous wall thickness monitoring of your asset.

Tradition corrosion monitoring techniques requiring manual ultrasonic thickness measurements are expensice due to the cost of gaining access to the pipe for measurement, oftern requiring pipe excavation, coating removal, sensor placement,etc. GE's Rightrax system continuously monitors corrosion at a fraction of the cost while providing frequent and reliable information that significantly improves decision-making.

Key Features and Benefits
* Non-intrusive inspection-Sensor simple bond or are clamped onto the inspection area
* Remote Locations- Offshore platforms, remote pipeline sites or other inaccessible areas
* No scaffolding or excavation costs- Once correctly installed no need to revisit the site and no active maintenance required
* Early warning systems- Software provides trending, warning and alarm information with data on demand
* Accuracy-Measurement repeatablity to 0.2 mm (0.008")(low temp) or 0.0025mm (0.0001")(high temp)
* Operator safety- Eliminates the need to spend operators intos hazardous environments or remote locations to carry out wall thickness monitoring
* Optimization of maintenance schedules- Saves valuable time by eliminating unnecessary inspections
* Predictive maintenace-Understanding the effects of gas and crude oil quality on pipe or asset integrity
* Increased asset integrity- The application of direct wall thickness monitoring can easily be justified when you consider:
* Unscheduled shutdowns (i.e.loss of production)
* Outage planning
* Hazard to personnel
* Environmental expousure

  • Riser piping
  • Mud piping
  • Slurry line pipping
  • Cross-country pipping
  • Pressure vessels
  • Sensor System: 14 single element probe attached to pipe using acoustic tape
  • System thickness resolution: The resolution of the thickness reading through the complete system is the smallest change that can be reliably detected. This is influenced by short-term temperature fluctuations. These variations will result in changes in the temperature profile across the pipe wall.
  • Thickness accuracy: Accuracy depends on correct system configuration of material velocity. Calibration standards or material specifications of the material are required for accurate results. This accuracy applies for uniformly corroded inside wall. Highly localized pitting may not be detected.
  • Tickness resolution single reading: With temperature variations at rates less then 1C (33.8F) per minute over a 5C (41F) range, the resolution is improved to the value obtained using regression analysis.
  • Total number of sensors per attached data logger: Using 10-way multiplexer
  • Total number of data loggers per line driver: Each driven by a 10-way multi-core cable with a maximum length of 260 m (853 ft)
  • Maximum total number of sensor extension cable per system: An individual sensor can have up to 70 meters of extension cable, but the total length of extension cable for the whole system cannot exceed 450 m (1476 ft)
