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.
