摘要：A method of assembling a steam turbine includes positioning a sealing member in a leakage path defined between a first stage nozzle diaphragm and a packing casing, wherein the first stage nozzle diaphragm has a first coefficient of thermal expansion, and the packing casing has a second coefficient of thermal expansion, and coupling the first stage nozzle diaphragm and the packing casing such that the sealing member is fixedly secured between the first stage nozzle diaphragm and the packing casing.
