Peer- review under responsibility of the 6th International Conference “Fracture Mechanics of Materials and Structural Integrity” organizers The paper deals with the issues of an application of acoustic emission (AE) method of continuous monitoring, with prediction of breaking load. System of continuous AE monitoring of pipelines of hot industrial steam overheating in power unit #1 at Kiev TPP-6 has been developed and put into trial operation. Preliminary the acoustic properties of steam pipeline materials were studied; high-temperature AE studies of steam pipeline material were conducted. Developed procedure allows determination of structure material breaking load, based on AE data, under actual operating conditions of the structure at any mo ent of time, irrespective of operating time volume or temperature variations. Breaking load predicted by continuous AE onitoring system is determined with accuracy sufficient for practical purposes. To ensure the time margin when taking the decision on the monitored facility state, safety factors were established for the predicted breaking load, which are automatically determined by the monitoring system, depending on the degree of danger of the destructive processes developing in the material. Monitoring schematic and features of practical application of monitoring system are presented. Applied procedure and technology allow determination of the coordinates of monitored facility section with minimum breaking load magnitude. Remote access allows performance of author’s supervision of system operation through the Internet. © 2019 The Author(s). Published by Elsevier B.V.
