Abstract: 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.

Abstract: The present pipe elbow includes at least two straight pipe sections joined together along a Y-seam, for example by welding. The Y-configuration of the seam is such, that the three limbs thereof all have the same length, whereby these limbs meet at a point off center relative to the central axis of the pipe. The elbow is formed by making a straight cut at right angles toward the longitudinal axis of the pipe and slightly through said longitudinal axis and by further cutting the straight pipe at acute angles so that second and third cuts meet the first cut at said off center point. These cuts result in wedge segments which fit exactly into the space between the arms of the Y-configuration when the pipe edges are joined along the leg of the Y-configuration. Thus, the present process does not produce any waste whatsoever.

Abstract: This coupling comprises a rotary cylindrical portion which is recessed and an outlet opening whose lower edge is placed level with the lowest point of a surface which is inclined relative to the rotation axis, whereby the said surface is placed adjacent to the axis and the side opposite to the said opening.This coupling is more particularly intended to be used on the inlets and outlets of pneumatic automatic control modules.

The elbow may be formed by serving a straight pipe along a plane normal to the axis of the pipe on one side of the center plane thereof and along a pair of planes at acute angles to the axis of the pipe on the other side of the center plane, to form a pair of pipe sections and a pipe segment. The edges of the pipe sections formerly connected to the pipe segment are joined together, and the pipe segment is joined to the ends of the pipe sections at the other side of their respective center planes.
