Tests of pipeline-inspection equipment based on principles of magnetic flux leakage have shown it to be capable of routine maintenance and to provide technical and economic advantages over hydrostatic testing. The equipment accurately locates and describes metal-loss defects and enables a pipeline's condition to be determined before a feature becomes critical. Further, equipment capable of detecting and sizing a range of different stress-corrosion cracking (SCC) geometries and types has also been developed and prototypes successfully evaluated during live gas tests in operating pipelines.
