ABSTRACT:
A flow splitter directs inlet steam in axially opposite directions in a double flow steam turbine. The flow splitter includes a main ring having a radially outer apex with annular concave surfaces extending inwardly from and in opposite axial directions on opposite axial sides of the apex. A second ring is secured on one axial side of the main ring by welding to the main ring and has a concave outer surface portion which completes the concave surface of the flow splitter along the opposite axial side of the flow splitter.
