FIELD: machine building.
SUBSTANCE: invention is related to methods of non-destructive check and is intended for determination of deposits thickness on internal surfaces of pipelines. In method of deposits thickness determination on internal surface of pipelines, which comprises measurement of pipeline surface temperature, on pipeline, coaxially to it, heat source is installed in the form of ring, temperature gradient is taken in direction from heat source along pipeline on its surface and, thereby, judgement is made on size of deposits inside the pipeline.
EFFECT: higher accuracy of deposits thickness determination on internal surface of pipelines, expansion of its possible application field and efficiency of technical execution.
