A method for determining cracks on the inner surface of a vitrified coating of a pipe using a defectoscopic installation is considered. The technological scheme is presented and the operating principle of the developed installation is described. According to the readings of the parameters of the installation, the electrical resistance of the cracks of the vitrified coating of the pipe was determined. The calculation of the main dimensions of cracks in coatings along the entire length of standard pipes is presented.
