Life Assessment

 

 

 

 

 

 

 

 

 

In the normal service life of a Superheater, failure usually occurs by a creep or stress-rupture mechanism. DNFM is able to evaluate remaining tube life of your superheater or reheater tubes.

 
Life assessment includes the following engineering services:
  • Microstructural characterization
  • Dimensional and hardness measurements
  • Estimation of operating temperature and design temperature
  • Calculation of operating stresses
  • Larson-Miller parameter (LMP) evaluation and Plotting the operating stresses and LMP on pre-defined curves.
