A composite horizontally split casing includes an inlet end having upper and lower cast inlet end sections, an outlet end having upper and lower cast outlet end sections, and separable upper and lower semi-cylindrical shell sections extending axially between the inlet and outlet ends. The upper semi-cylindrical shell section is welded at opposite ends respectively to the upper inlet and outlet end sections to form an upper casing half. The lower semi-cylindrical shell section is likewise welded at opposite ends respectively to the lower inlet and outlet end sections to form a lower casing half. External bolting flanges on the upper and lower casing halves provide the means by which the upper casing half is mounted on the lower casing half. |
