Initial Tension of Local Primary Internal Eddy Current Transformer of Transformer Type is in a Electric Conduction Ferromagnetic Pipe
At diagnosticating of the technical state of main pipelines (gas pipelines) violations of wholeness find out defects as, set the actual thickness of wall of pipeline, and determine to the profile of his surface. On the basis of acoustic (ultrasonic), magnetic and eddy current methods of control intellectual pistons that is used for inwardly pipe technical diagnostics are worked out. Eddy current a control method gives an opportunity to educe superficial cracks with the small opening and defects of stratification of metal of pipeline.
