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.
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
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:
