The Importance of Monitoring
The negative effects of corrosion and erosion cost the oil and gas industry billions of dollars every year in unscheduled plant or pipeline shutdowns, lost production, high repair costs or imposed fines. Experts believe that 20 to 25% of corrosionrelated costs could be avoided. Corrosion and erosion data
monitoring technologies are an important first step toward realizing those savings.
Aside from serious cost implications, operators in this demanding industry must consider the incalculable damage that results from potential employee injuries and the effect of spillage on an organization’s reputation.
Maximum Uptime, Minimum Inspection Costs
GE’s Rightrax and Rightrax HT systems are changing the way that critical corrosion data is measured and managed.
This breakthrough technology helps increase safety and productivity while reducing overall inspection costs.
The Rightrax system uses permanently installed sensors that permit remote monitoring of restricted or high-temperature areas up to 350°C. Once fitted, the system provides remote access to corrosion data, eliminating the need to erect scaffolding, remove insulation or shut down plants. Online monitoring also reduces costly and labor-intensive planned maintenance schedules and traditional inspection routines.
More Than Just Wall Thickness Measurement
• Provide accurate feedback to manage opportunity crude processing in a refinery by monitoring effects on pipe wall thicknesses
• Help correlate Total Acid Number (TAN) to corrosion rates
• Provide support for chemical injection programs by supplying accurate and reliable pipe wall thickness data
• Improve control of corrosion rates by optimizing the corrosion inhibitor addition process.
• Provide additional inspection capability for pigging operations, especially for critical spots and nonpiggable sections
Make informed decisions, reduce total corrosion costs
• Interface with plant asset management systems, such as GE OC System 1, viewing fixed and rotating asset conditions in a single system
• Correlate critical process parameters such as flow, temperature, pressure, crude quality and chemical injection to pipe wall thickness variation to optimize process decisions
• Export corrosion rate information to expert systems (such as OC System 1) for intelligent alarming and modeling
Rightrax LT (Low Temp) System
Online, consistent, reliable wall thickness measurement up to 120°C (248°F) applications
Traditional corrosion monitoring techniques requiring manual ultrasonic thickness measurements are expensive due to the cost of gaining access to the pipe for measurement, often 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.
Rightrax HT (High Temp) System
A new paradigm...Continuous wall thickness measurement of pipes and
vessels operating at temperatures up to 350°C (662°F)
Using breakthrough ultrasound technology to detect small changes in pipe wall thickness with permanently installed sensors, Rightrax HT enables you to quickly identify changes due to corrosion or erosion. Leveraging the power of GE Fanuc Intelligent Platforms' Cimplicity software, the system enables the user to monitor rate changes, alarm before possible upset conditions, and interface with other plant asset management systems, such as System 1 and decision support models, for
improved uptime and overall plant safety.
