Inspect the UNPIGGABLE

AGIT, a revolutionizing inspection technology that overcomes limitations of ILI and ECDA 



Localization & categorization of metal loss
and coating defects



Inspection of all commonly operated types of unpiggable pipelines is possible



Certified and successfully used around
the world


Inspection Advancement
through Innovation

Electromagnetic Pipeline Testing GmbH is a worldwide leading company in the research area of sensitive magnetic field measurements for the purpose of non-destructive testing. Years of intensive scientific research, experiments and dedication have enabled to bring something new to pipeline industry:

An inspection technology that is able to assess pipeline conditions from aboveground. This inspection technology is called AGIT (AboveGround Inspection Technology). Both, the inspection technology and the inspection system are certified and tested through TÜV Süd.


View TÜV-Süd-Certificate

use AGIT

Locate internal and external corrosion, blisters, gauges, defects in girth welds and mill features

Locate metal loss under disbonded coating

Locate coating damages and differentiate them from metal loss features

Locate metal loss under undamaged coating (corrosion under insulation)

Measure Depth of Cover with a certified accuracy of 20 mm

Find and map pipeline routes with a certified sub-decimetre accuracy

Locate girth welds, casings, bends, stuck pigs, obstacles aboveground and metal parts close the pipeline

Verify the pipeline route from aboveground (ROW Inspection)


Overcome limitations of ILI and ECDA

Save money by reducing excavations as corrosion under coatings and coating damages with no corrosion underneath can be differentiated

Save money by reducing excavations as sizing of detects is possible with 4 different levels

Save money by reducing the size of excavations as feature coordinates have sub-meter accuracy

Survey of growing faults caused by corrosion over time

No preparation for the inspection is needed (e.g. cleaning/ opening the pipeline)

No influence on the operation of the pipeline while inspection is executed

A safe and cost-effective technology that is certified and has been used by pipeline operators around the world

Defects detected
through AGIT

AGIT has been used to inspect hundreds of kilometres of unpiggable pipelines. Recent optimizations have helped to make the field inspection system more productive and price-efficient.
