Performance and Life Assessment of Reformer Tubes in Petrochemical Industries

High temperature mechanical properties of
service exposed reformer tubes are compared and revalidated
with those of virgin material for the sake of health
assessment studies. Technical interpretations of creep
and stress rupture (accelerated creep) data usually are in
close proximity in absence of defects. Results of extrapolation of accelerated creep data were optimized. This review article is aimed at studying life prediction methodology of reformer tubes operating at high temperature and aggressive chemical environment, in response to the designed time frame for preventing failures and accidents, even before stipulated design time schedules in some cases.
