Structural integrity of a standpipe component in a petrochemical catalytic cracking unit: part 2- assessment of embrittlement effects
Article Abstract:
Results reveal that the carburization of the standpipe steel grain boundaries was caused by atmospheric carbon monoxide and carbon dioxide content. Data further point out that chromium content was lower in the grain interiors rendering them susceptible for oxidation due to high temperature.

The linkage between microscopic cavitation damage and macroscopic crack growth
Article Abstract:
Research examines the growth of a pre-existing crack in a creeping material by grain boundary cavitation. Data from a micromechanical model indicate that the damage shows a branching mode of crack growth that is dormant and symmetric to the crack plane.

Structural integrity of a standpipe component in a petrochemical catalytic cracking unit: part 1- assessment of creep rupture properties
Article Abstract:
Results show that the ex-service material retained a 10-year residual life as indicated by the accelerated creep tests. Data further show that the heat-treated material suffered adversely in creep strength with time.
