Abstract: An in-situ probe technique with an outward attached type of electrochemical sensor for inspection and evaluation of the susceptibility to sulfide stress corrosion cracking (SSCC) and hydrogen embrittlement (HE) of pipeline/vessel was developed. The relationship between SSCC/HE susceptibility of steel UNS G10180 and UNS G11190 and I-H was determined by the measurement of the stable hydrogen permeation rate (I-H) and the study of SSCC/HE susceptibility of the above two steels in TM-01-77 solution. Environmental sensitive cracking (ESC) of UNS G10180 and UNS G11190 steels can be inspected, evaluated, judged by the combination with the microcomputer system (MCS)/periphery attachment and the designed software. The results give an important insurance for safety control of the pressurized pipeline/vessel operated in the environment with H2S.
