Conclusion
• Individual technologies have limitations when used
independently as defined by industry standards such as NACE
SP0102-2010
• Multiple DataSets, with SpirALL® MFL Technology, is proven to
enhance characterization and sizing for most integrity threats
and:
• Overcome limitations of individual technologies
• More effectively detects and characterizes crack-like and
metal loss anomalies
• Provide a foundation for determining pipe properties
• Provide comprehensive mechanical damage assessment
and prioritization
• Eliminate unnecessary excavations
