... will exhibit a higher creep rate and will fail earlier than expected. Predominant locations for creep failure are: (1) just prior to a change to a higher grade of steel; (2) just prior to the final outlet header, where the tubing and steam temperatures are the highest; and (3) where the radiant-heat effect can...

.... These cracks are transgranular in nature and usually filled with scales. Cracking due to corrosion fatigue is often found close to regions of physical restraint such as connections to inlet or outlet headers, the toe of the weld, a weld undercut, corrosion pits, notches, or similar other sites. Cracks may...

... in volume, requiring increasing diameter and longer blades at each successive stage to extract the remaining energy. Superheated and pressurized steam is first allowed to expand in an HP steam turbine, which causes rotation of the turbine shaft. The outlet steam from the HP turbine is reheated and made...

The outlet steam from the HP turbine may once again be reheated and made to expand through an intermediate-pressure (IP) turbine and then through a low-pressure (LP) turbine. The turbine shafts are all connected to one or more generator shafts which in turn rotate...
