Vibrodiagnostic motion control of intratubal objects in gas pipeline

摘要

A comparative analysis of the amplitude-frequency characteristics of elastic waves detected vibration measuring transducer on the outside of the tap pipeline security when moving in a gas-tube include cleaning pigs, shell-pattern navigation caliper. Describes the principle of operation and the results of the test device for the posting at any point on the external surface of the pipe to determine in real time to within a few meters of the location and speed of intratubal objects at distances of over 25 km.
