Remaining life assessment of a high pressure turbine

What is it about?

Open access article. Based on the comprehensive investigation, the results of residual life assessment of one high pressure steam turbine casing, which belongs to the older turbine generation, taking into account simultaneous action of thermal fatigue and creep, are presented in this paper. Also, the critical flaw crack size of HP turbine casing is determined because this parameter has a strong influence on casing integrity and residual life.

Why is it important?

The results of residual life assessment provide not only a basis for further maintenance, but also estimated time for reparation or renewal.
