17G1S steel is widely used in pipelines. Change in the physical properties of this material with time depends on the conditions of gas pipeline operation and pipe environment. Material damage due to operating time by far not always leads to a change of such standard characteristics of the material as σt, σy, К1С and a number of others. At the same time, such material can be significantly damaged, but the traditional methods do not allow determining it. The objective of this work is to demonstrate the sensitivity of acoustic emission method to changes in 17G1S steel properties after 15 years of the main gas pipeline operation. Testing results show that the analyzed acoustic emission parameters change essentially under the impact of operating time, and they can be the characteristics for evaluation of the current state of the damaged material. 6 Ref., 5 Fig.
