METHOD FOR AUTOMATED EXTERNAL DIAGNOSTICS OF PIPELINE AND AUTOMATED DIAGNOSTIC COMPLEX FOR ITS IMPLEMENTATION Russian patent published in 2021 - IPC G01N29/04 

FIELD: pipeline control.

SUBSTANCE: invention is used for external diagnostics of industrial pipelines, bridges and sections of pipelines that are not subject to in-line diagnostics, as well as for monitoring welds during the construction and repair of pipeline sections. The essence of the invention lies in the fact that due to the automation of the pipeline diagnostics process and the use of a rigid mechanical structure with laser and ultrasonic measuring systems, it is possible to measure the external geometry of the pipeline and perform non-destructive testing of the outer surface, the base metal of the pipeline, welds and the weld proximity without additional operations for reinstalling and positioning the diagnostic complex, to process the received diagnostic, coordinate and telemetric information from ultrasonic and laser measuring systems, encoders, optical tracking sensors, and with the help of an operator to determine the type, position and geometric parameters of external, internal and intra-wall defects in real time.

EFFECT: improvement of the accuracy of determining the location and measuring the geometric parameters of defects in the base metal of the pipeline, longitudinal, transverse, spiral welds and the weld proximity.
