Material Degradation and Life Prediction

Plant owners depend on reliable and accurate assessment of boiler or high temperature vessels in both emergency and planned outages. That is why Metserve has designed a Condition Assessment program to determine the current condition of your boiler, pressure part components and/or its auxiliaries. From the information gathered during inspection and metallurgical evaluation, the goal is to document the condition and to report findings. Recommendations can then be made to remedy the problems.

Many utility systems in the world have power plants operating with fossil fuel with service life crossing 100,000 hours of operation. These units are subjected to time dependant degradation phenomena such as :

a.

high temperature tensile failures

b.

creep and rupture failures

c.

low cycle fatigue at elevated temperatures

d.

hydrogen embrittlement

e.

hot corrosion / erosion failures
