A method is provided of producing a housing with two layers. The method includes casting an inner casting formed as an inner layer, and then casting an outer casting. The inner casting is used as a wall and the outer casting is formed as an outer layer. The inner layer is made of a more heat resistant material than the outer layer. Hooked formations are fitted on the inner casting in order to improve an integral bonding to the outer layer.

Process for producing a turbine housing and turbine housing

A turbomachine including a rotor and an inner interior housing an outer interior housing and an exterior housing, wherein the turbomachine has a first flow and a second flow arranged opposite the first flow for a high-pressure blading or medium-pressure blading, wherein the inner interior housing is made of a higher quality material tan the outer interior housing and solely accommodates the high-pressure and medium-pressure inflow regions including the balance piston is provided.

Steam turbine in a three-shelled design

In order, in a particularly simple way, to allow multiple separation and connection of line sections of a line, through which a hot and highly compressed medium flows, in particular a pipeline, through which steam flows, there is provided a double-walled flanged connection. The double-walled flange connection is formed of an outer flange and an inner flange, between which an interspace, through which a cooling medium is capable of flowing, is formed. The apparatus is particularly suitable for the connection of line sections of a steam turbine.
