STEAM TURBINE FACILITY |
摘要 |
It is intended to provide a steam turbine facility which is capable of appropriately sealing a gap between members made of cast material of Ni-based alloy even under the steam-temperature condition of 650°C or higher. In a steam turbine facility 1, a first member 32 and a second member 34 whose base material is formed of cast material composed of at least one of Ni-based alloy, austenite steel, or high-chrome steel, form a space where the steam of 650°C or higher flows. Between the first member 32 and the second member 34, a metal gasket 60 or 80 is provided. The metal gasket 60 or 80 has a plurality of portions in line contact with the first member 32 and the second member 34. On the first member 32 and the second member 34, a first high-hardness layer 56 which is harder than the base material, is provided at least in a portion where each of the first member 32 and the second member 34 is in line contact with the metal gasket 60 or 80. |
