    Abstract: The method for removing an inner casing from a machine such as a turbine or compressor includes providing supports between the outer casing and the inner casing of the machine, removing a top part of the outer casing, then removing a top part of the inner casing, then connecting a ring sector to a bottom part of the inner casing to replace the removed top part of the inner casing, then rotating the reciprocally connected ring sector and bottom part of the inner casing around the longitudinal axis to make the bottom part of the inner casing accessible, then removing the bottom part of the inner casing, guiding the reciprocally connected ring sector and bottom part of the inner casing during rotation, to prevent movement along the longitudinal axis.

    Abstract: A turbine includes an outer casing and an inner casing surrounded by said outer casing. The outer casing and inner casing are coaxially arranged with respect to a machine axis. The outer casing and inner casing are each divided in a split plane into an upper part and a lower part. The upper and lower parts are connected with each other in said split plane by means of a flanged connection. The disassembly process is improved by the flanged connection of the upper and lower part of the inner casing comprising a plurality of bolts, which extend each through through holes in respective flanges of said flanged connection of the inner casing, protrude from said through holes at both ends with a threaded section, and are tightened by means of nuts screwed on said threaded sections at both ends of said bolt.

    Abstract: A tool for installing or uninstalling a segment of an inner housing of a turbomachine. The turbomachine includes an outer housing, at least partially surrounding an inner housing and a rotor, concentrically arranged within the inner housing. The rotor is equipped with a number of rotor grooves. The inner housing is divided at an essentially horizontal split plane into an upper segment and a lower segment. The tool includes a first portion insertable into any of the rotor grooves, and furthermore includes a second portion disposed at a distance from the first portion. This second portion is connectable to the lower segment of the inner housing.
