Predicting the remaining life of components operating in the creep regime is one of the trickiest problems encountered in the fitness-for-service (FFS) world. Heater tubes, steam methane reformer tubes, and FCCU’s are a few of the components that can experience a combination of high temperature, stress, and long exposure resulting in the insidious degradation of the material via the process referred to as “creep.”
Creep behavior is easy to describe.
Creep is the time-dependent deformation of a material under load.
