• Arms ride directly on the pipe wall for

greater sensitivity to ID changes

• Circumferential arm spacing approx.

0.25” (6.35mm) when collapsed in ID

• High resolution offers strain capability

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
