The 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 technique that is able to assess pipeline conditions from aboveground. This inspection technique is called AGIT (AbouveGround Inspection Technique)

Both, the inspection technique and the inspection system are certified and tested through TÜV Süd.

The EMPIT technique is designed for the inspection of unpiggable pipelines

Benefits

01Differentiation between metal loss defects and coating/ insulation defects

02Localization of corrosion, blisters, dents, gauges and mill features 

03Localization of defects in the inner and outer wall of the pipeline

04Localization of metal loss under undamaged coating (corrosion under insulation)

05Localization of metal loss defects under disbonded coating

06Localization of girth welds

07Operation can be done with any commonly applied type of coating

08Sizing of defects with 4 different levels

09Pinpoint defects with sub-meter accurancy

10No preparation for the inspection is needed (e.g cleaning/ opening the pipeline)

11No influence on the operation of the pipeline

12Safe and cost-effective


Features detected through EMPIT technique 

Defects detected through AGIT

AGIT has been used to inspect hundreds of kilometres of unpiggable pipelines. Recent optimizations helped to further decrease AGIT's response threshold (minimum peak metal loss detection) while simultaneously becoming more productive and price-efficient. 

Examples of features detected with the EMPIT inspection technique:
