Abstrakt: |
A thin-walled 18Cr/10Ni/Ti stabilised austenitic steel tube was exposed to CO2containing 1 vol.- % CO and 0·1 vol. % CH4and 80–90 ppm H2O at 20 atm (285 psig) and 600 610° for 1000 hours in an Advanced Gas Cooled Reactor. The external surface of the tube over which the gas flowed remained in good condition, but in the bore, where the gas was effectively static, grossoxidation and carburisation occurred. Microscopical examination and thermodynamic considerations lead to the conclusion that static gas conditions favoured the attack observed in the bore but poor surface finish may have initiated it. |
