The cross over expansion joint located in the piping between the steam turbine and condenser hood is often not understood well and often ignored.

To avoid long unscheduled outages, Steam turbine manufacturers recommend having these rebuilt after 25 years in operation.
This is a video that is of interest to maintenance, steam and turbine engineers, and inspectors.
