FIELD: measuring equipment.
SUBSTANCE: invention relates to a measuring equipment and can be used to determine the position of a pipeline in space, for example, in the horizontal and vertical planes during operation and construction of pipelines. Method is proposed for measuring the bending radius of a pipeline based on the data of a diagnostic complex for determining the position of a pipeline with an integrated, free-of-charge inertial navigation system mounted on an in-line inspection device that is moved inside the pipeline, after the in-line inspection device is passed through the pipeline, the diagnostic data obtained is recorded on the on-board information storage device installed on flight data recorder, and the diagnostic data obtained from the platformless inertial navigation system is transmitted from the flight data storage device to the bending radius measuring device included in the stand-alone complex for interpreting the diagnostic data that is located outside the pipeline and by measuring the bending radiuses of pipeline by measuring the large bending radius of the pipeline from 100 to 2,500 DN.
EFFECT: technical result is the expansion of functionality based on the measurement of dangerous (100…500 DN) and non-hazardous (500…2,500 DN) from the point of view of destructing the pipeline of large radius of vertical or horizontal pipeline bending, including near the taps of the pipeline with a small bending radius (1…100 DN), where DN is the internal nominal diameter of the pipeline.
