Amethod of identifying cracks on the inner surface of a glazed coating on a pipe with aid of a flaw detector is examined. The technological scheme is presented and the principle of operation of the developed apparatus is presented. The electric resistance of cracks in the glazed coating of a pipe is determined in terms of the parameter readings of the apparatus. A calculation of the basic dimensions of cracks in coatings along the entire length of standard pipes is presented.
