The paper deals with the issues of application on the basis of acoustic emission (AE) method of continuous monitoring of hot industrial steam overheating pipelines in operation with prediction of breaking load. Possibilities of introducing AE method for continuous monitoring of pipelines of power unit No1 of Kiev TPP-6 were analyzed. Acoustic properties of steam pipeline material were studied. Preliminary high-temperature AE studies of steam pipeline material were conducted. Mounting and testing of continuous AE monitoring system, its putting into trial operation, and correction of settings on the basis of obtained measurement results were performed. It is shown that breaking load predicted by AE continuous monitoring system is determined with accuracy sufficient for practical purposes. Control schematics and features of system practical application are presented.
