This study is devoted to the study in diagnostics of macro-micro cracks in pipes coated with silicate-enamel, which is a key problem for the structural integrity of piping systems. Silicate-enamel coatings are commonly used to improve corrosion resistance, but the identification of subsurface macro-micro cracks remains challenging. Despite the fact that the process
of diagnosing macro cracks on the surface of the coating is currently underway, the issue of diagnosing macro-micro cracks is still problematic. The article emphasizes the importance of timely detection in order to prevent possible leaks and design failures, emphasizes the consequences for economic development and security. An algorithm for diagnosing microcracks on the surface of pipes with silicate-enamel coating has been developed. The test voltage of the improved electric spark flaw detector was increased to 40 kV, and microcracks of up to 1.5 mm were detected. A method of remote detection of oil leaks from oil trunk pipelines is described. As a result of the diagnostics, the coordinates and geometric parameters
of the cracks are determined.
