Abstract
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.
Claims2
A composite horizontally split casing comprising:
- an inlet end having upper and lower seamless inlet end sections, one of which is provided with an integral inlet nozzle;
- an outlet end having upper and lower seamless outlet end sections, one of which is provided with an integral outlet nozzle;
- a generally cylindrical rigid shell fabricated separately from and extending axially between said inlet and outlet end sections, said shell being subdivided into upper and lower semi-cylindrical shell sections, said upper semi-cylindrical shell section permanently joined at opposite ends respectively to said upper inlet and outlet end sections to form an upper casing half, said lower semi-cylindrical shell section permanently joined at opposite ends respectively to said lower inlet and outlet end sections to form a lower casing half;
- external bolting flanges on said upper and lower casing halves, said bolting flanges having end segments which are formed integrally with said end sections and intermediate segments which are permanently joined to said shell sections;
- and means cooperating with said bolting flanges to removably mount said upper casing half on said lower casing half.
