| Abstract: | The microstructure and mechanical properties of an ethylene cracking tube (36XS Alloy) which has been exposed for 5 years are investigated. It has been found that the creep rupture strength is reduced and the tube wall is thinned after long time exposure.A residual life predication method of cracking tube is proposed taking account of the creep damage and the thinning damage of the tube. |
