Abstract (en)
The turbine (1) has a rotor (3) rotatably supported in an inner housing (4), and an outer housing (5) arranged around the inner housing. The housing (4) has an axial parting line and a radial parting line (12), and the housing (5) is designed as cup-shaped housing. The housing (4) has inner housing parts (4a, 4b) and another set of inner housing parts (4c, 4d) that are arranged behind the parts (4a, 4b) in an axial direction. The parts (4a, 4b) are made of a nickel-base-material, and the housing (5) is installed firmly with a ground. The parts are connected with one another via a flange (16). An independent claim is also included for a method for manufacturing a steam turbine.
