Stress corrosion cracking tendency of steel St. 3 in hydrogen sulfide-saturated monoethanolamine solutions. Dokuchaev, V. A.; Archakov, Yu. I. (USSR). Kontrol, Remont Zashch. Korroz. Neftezavod. Oborud., 60-9. Edited by: Martynov, N. V. TsNIITEneftekhim: Moscow, USSR. (Russian) 1982. CODEN: 51WCAI. DOCUMENT TYPE: Conference CA Section: 72 (Electrochemistry) Section cross-reference(s): 55 The behavior of structural steels and the effect of different factors on their tendency to undergo stress corrosion cracking (SCC) in monoethanolamine (I) [141-43-5] satd. with H2S [7783-06-4], at different concns. and temps., were studied. The effect was also studied of different additives and inhibitors on the electrochem. behavior and tendency of steel St. 3 [39296-41-8] to undergo SCC. This tendency of C steels to undergo SCC in hot solns. of I, both pure and contg. different impurities, develops at an electrochem. surface potential more neg. than -700 mV (vs. a AgCl electrode). The steady-state potential of steel St. 3 is shifted in the neg. region during an increase in concn. of I solns. and during an increase in their temp. In this case, the tendency toward SCC increases. Hot H2S-satd. solns. of I, on the other hand, make the steady-state potential of steel St. 3 more pos., decreasing its dependence on the temp. and decreasing its tendency toward SCC. The addn. to the soln. of I of an increased concn. of inhibitors of the overall corrosion (NH4VO3 [7803-55-6] and IFKhANGAZ-1 [69899-55-4] (corresponding to 500 and 30 g/L, resp.)) shifts the surface potential of the steel St. 3 into the pos. region, which to some degree lowers its tendency toward SCC in sites of I concn.
