FIELD: pipelines testing.
SUBSTANCE: invention relates to in-line non-destructive testing of pipelines. The substance of the invention lies in the fact that the in-line magnetic measuring system consists of segments mounted on the body and distributed along the circumference around the central axis, with each segment consisting of three hinged links. The segments are mounted on wheel supports, which are fixed to the body on both sides, and suspensions with sensor blocks are fixed on the base.
EFFECT: improving the accuracy of assessing the actual state of the pipeline during in-line diagnostics and ensuring the possibility of flaw detector operation in the forward and reverse directions.
