4 ILI Technology Overview Caliper High Resolution Geometry Axial MFL Circumferential MFL Helical MFL Residual Field or Low Field MFL Inertial Mapping/XYZ Combination Technology UT Wall Thickness UT Crack Detection EMAT

5 Caliper Low Resolution geometry and bore measurement technology. Optimal tool speed 3-5mph.

6 Caliper Integrity Assessment Dents and bends (detect and size) Low resolution geometry technology primarily used for New Construction inspections. Optimal tool speed 3-5mph. Gas or Liquid pipelines

7 High Resolution Geometry

8 High Resolution Geometry Dents, bends, wrinkles, buckles, expanded pipe, and evidence of strain. (Detect and Size) Tool Speed 3-5 mph Gas or Liquid pipelines. 3 to 56.

9 High Resolution Geometry Estimated WT = ( ) (9.53mm) (7.93mm) (6.35mm)

10 High Resolution Geometry

11 Axial MFL Axial Field ***Magnetic field orientation plays a key role in detection, identification and sizing.**

12 Axial MFL Integrity Assessment Metal Loss internal or external. (Detect and Size) Dents, Wrinkles, Laminations and Bends. (Detect) Gas and Liquid pipelines

13 Axial MFL

14 Circumferential MFL (Transverse Field) Circumferential Field

15 Circumferential MFL (Transverse Field) Integrity Assessment Metal Loss internal or external. (Detect and Size) Selective Seam corrosion external and/or internal. (Detect) Axially oriented crack like manufacturing defects. i.e. hook cracks, etc. (Detect) Dents, wrinkles, laminations and bends. (Detect) Gas and Liquid pipelines

16 Helical MFL (Spiral Field)

17 Helical MFL (Spiral Field) Integrity Assessment Metal Loss internal or external. (Detect and Size) Selective Seam corrosion external and/or internal. (Detect) Axially oriented crack like manufacturing defects. i.e. hook cracks, etc. (Detect) Dents, wrinkles, and laminations. (Detect) Gas and Liquid pipelines. 6-30

18 Residual or Low Field MFL Integrity Assessment Hard Spots (Detect). Strain (Detect). Gas and Liquid pipelines

19 Combination Technologies Combine different technologies to allow for a standalone tool run (4-56 ). Tool Speed 3-5 mph. Gas or Liquid pipelines.

20 Combination Technology (GEO+Axial MFL)

21 Inertial Mapping/ XYZ Evidence of strain, bends and curvatures. (Detect and Size) Tool Speed 3-5 mph. Sub meter coordinates of pipeline features (valves, etc.) and anomalies (corrosion, dents, etc.). Gas or Liquid pipelines.

22 Inertial Mapping/ XYZ

23 Ultrasonic Wall Thickness Induces normal beam UT into pipe wall. Liquids only or needs to be run in a batch of diesel or water. Pipeline needs to be very clean and tool speed needs to be 1-3mph

24 Ultrasonic Wall Thickness Integrity Assessment Metal loss internal and external. (Detect and Size) Narrow axial external corrosion. (Detect and Size) Laminations. (Detect and Size) Dents, wrinkles and bends. (Detect).

25 Ultrasonic Crack Detection Induces signal into the pipe at a variety of angles. Pipeline needs to be very clean and tool speed needs to be 1-3mph. Liquids pipelines only or needs to be run in a batch of diesel or water

26 Ultrasonic Crack Detection Integrity Assessment Metal loss internal and external. (Detect) Selective seam weld corrosion. (Detect and Size) Axially oriented SCC, stress fatigue cracks, cracks and crack like manufacturing defects.(detect and Size). Narrow axial external corrosion. (Detect and Size) Laminations. (Detect and Size) Dents, wrinkles and bends.(detect)

27 EMAT Electro Magnetic Acoustic Transducer Pipeline needs to be very clean and a optimal tool speed around 1-3mph. External and internal corrosion, selective seam weld corrosion, axially oriented crack like defects, dents, etc. (Detect) Axially oriented SCC, cracks and hard spots. (Detect and Size) Gas and Liquids Pipelines
