METHOD FOR NON-DESTRUCTIVE TESTING THICKNESS deposits on the inner walls of pipelines based on radioisotope radiation

摘要

A method of nondestructive testing Fat thickness on the inner wall of the pipe, comprising a wave emission commissioning test pipe is measured by the radiation from the opposite side, is calculated intensity of radiation transmitted through the tube formed the ratio of the radiation respectively with a value of the intensity of radiation transmitted through a similar tube without internal deposits to assess thickness Fat, characterized in that the pipe under investigation is irradiated with a narrow beam of radiation radioisotope conduct registration n otok direct gamma radiation after interaction with the total flow, e.g., oil and fat, followed by calibration of determine the deposition thickness, adjusting the gamma-ray intensity, the exercise forming the corresponding information signal in the form of discrete samples in the sample a predetermined volume , then separated from the informative signal generated during the registration sequence of samples corresponding to a clean tube without sediment and determine thickness Susp eny by processing the measurement results transmitted radiation by altering the intensity of the radiation as it passes through various medium, for example a material conduit, a layer of paraffin oil moving.
