The disclosure relates to the construction of large fluid conduits and particularly to steam conduits used in large power plants. In some power plants, steam is transferred from the exhaust of a higher pressure turbine section into the inlet of a lower pressure turbine section through a steam conduit sometimes referred to as a cross-over which may include several bellows type joints. If the turbine rotor speed exceeds rated speed, then it is desirable to limit the maximum speed to be attained by the turbine rotor. The present invention provides a reliable and advantageous construction which will decrease the maximum speed of a turbine rotor over designs now available in the prior art. |
