Axial MFL

***Magnetic field orientation plays a key role

in detection, identification and sizing.**

Axial FieldAxial Field

Axial MFL

Integrity Assessment

• Metal Loss internal or external. (Detect and

Size)

• Gas or Liquid pipelines.

Combination Technology (GEO+Axial MFL)

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.

Inertial Mapping/ XYZ

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.

• 6”-56”.

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).

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.

• 6”-56”.

Ultrasonic Crack Detection

Integrity Assessment
