Abstract
This paper is aimed at investigating the damage and remaining life of a whole HP-Nb
hydrogen reformer tube serviced for 12 years. The damage and remaining life evaluation of
different parts of the tube were made using metallographic examination, ambient and high
temperature uniaxial tensile tests, creep rupture tests and damage mechanics analysis. The results
showed that different parts of the tube have the different damage and remaining life due to different
service temperature, higher the service temperature, severer the damage and shorter the remaining
life. Based on these research results, a case of local maintenance of the reformer tube was
introduced.
