Effects of thermal spray aluminium coating on SSC and HIC

Jul 04, 2020· Flexible risers are critical equipment for the production of oil and gas in offshore fields around the world. The annulus region may condense acidic wSulphide stress cracking behaviour of the dissimilar metal The sulphide stress cracking (SSC) behaviour of the dissimilar metal welded joint of X60 pipeline steel and Inconel 625 alloy in H 2 S environment was investigated using constant load testing, weight loss testing and finite element analysis. The dissimilar welded joint shows high SSC susceptibility, and the asymmetric stress concentration after corrosion is the prerequisite for crack initiation.The Effect Of Load Fluctuation On Sulphide Stress In practice, most plant undergoes load fluctuation, and the present study examined the effect of a small fluctuating load component on sulphide stress cracking (SSC) behaviour.
