Bidirectional MFL inspection of non-piggable pipelines.(magnetic flux leakage)

From: Pipeline & Gas Journal | Date: March 1, 2008| Author: van Beugen, Peter | Copyright information

Around half of all the world's oil and gas pipelines are non-piggable for one reason or another. There is growing interest in looking into the integrity of these pipelines. One tool has been developed that can cover at least a bulk part of these pipelines.

The new high-resolution magnetic flux leakage (MFL) tool incorporates all features of any up-to-date MFL inline inspection (ILI) tool. The surplus value of the tool is that it is bidirectional, multidimensional and has...
