Abstract
A turbine casing includes a plurality of arc-shaped segments having a flange at each side end to connect to a flange of an adjacent arc-shaped segment. The flange extends outward from an outer surface of each arc-shaped segment and extends along the outer surface in a front-to-rear direction. Each arc-shaped segment has a portion of the outer surface that is co-linear with the flange in a front-to-rear direction that does not include the flange.
Claims18
A turbine, comprising:
- a casing having a plurality of arc-shaped segments to together form a substantially circular cross-section shape of the casing, the casing having a front rim to define a front opening and a rear rim to define a rear opening, and the plurality of arc-shaped segments extending in a front-to-rear direction between the front rim and the rear rim;
- and
- an affixing protrusion extending radially from an outer surface of the casing at each junction of the plurality of arc-shaped segments to affix adjacent arc-shaped segments to each other,
- wherein the casing includes an annular region on the outer surface of the casing having no affixing protrusion, the annular region having a thickness from an inside surface to the outside surface less than a thickness of the casing at the affixing protrusion from the inside surface to the outside surface.

A turbine casing, comprising:
- a plurality of arc-shaped segments, each arc-shaped segment having a front rim at a front end, a rear rim at a rear end, and a flange at each side end to connect to a flange of an adjacent arc-shaped segment from among the plurality of arc-shaped segments, the flange extending outward from an outer surface of each arc-shaped segment and extending along the outer surface in a front-to-rear direction, each arc-shaped segment having a portion of the outer surface that is co-linear with the flange in the front-to-rear direction that does not include the flange, the portion of each arc-shaped segment that does not include the flange having a width from an inner surface of the arc-shaped segment to the outer surface of the arc-shaped segment that is less than a width of the arc-shaped segment at the flange from the inner surface of the arc-shaped segment to the outer surface of the arc-shaped segment.
