Wet hydrogen sulfide cracking of steel monitoring by acoustic emission: discrimination of AE sources

摘要: In the petroleum industry, it is known that equipments which operate in wet hydrogen sulfide (H2S) media can be subjected to damages like Hydrogen Induced Cracking (HIC) and Sulfide Stress (SSC). this study, Acoustic Emission (AE) technique used monitor cracking of steels immersed sour media. The aim establish a methodology for HIC SSC detection by AE therefore get more detailed information on mechanisms during standard tests. main focus article preliminary identification different sources involved tests performed signals monitoring steel grades are described. results indicate provide an early (HIC SSC) when various identified.
