Effect of wet H{sub 2}S cracking on the serviceability of carbon steel equipment in petrochemical service
- CLI International, Inc., Houston, TX (United States)
Knowledge of the operable wet H{sub 2}S cracking mechanism(s) and mechanical behavior of wet H{sub 2}S damaged material is required to properly assess the fitness of equipment for continued service versus repair or replacement because of wet H{sub 2}S damage. This paper presents the results of large-scale wet H{sub 2}S exposure tests which utilized a steel pressure vessel containing various welded test plates. Particular attention was given to (1) the performance of conventional carbon steels versus advanced carbon steels designed for enhanced resistance to wet H{sub 2}S cracking, (2) defining which wet H{sub 2}S mechanisms result in in-plane cracking as opposed to through-wall cracking and providing the typical locations in which they are observed, (3) the interrelationship of stress, welding and plate orientation on the susceptibility to wet H{sub 2}S cracking and (4) residual mechanical properties of conventional carbons steels used in wet H{sub 2}S refinery service. The results of this program have provided valuable insight on the role of steel quality and microstructure on the susceptibility to wet H{sub 2}S cracking and provided valuable data on the residual strengths and toughnesses of steels containing extensive wet H{sub 2}S damage.
