Casing All
steam turbines made by MANTURBO have a horizontally split casing of
cast steel. The guide vane carriers aresupported thermoelastically inside themain casing.State-of-the-art materials are used forthe casing and the guide vane carrier.The partition joint bolts are uniformly preloaded by an hydraulic tightening
device without the application of any torque. Bolt stresses can be measureddirectly during the assembly and the
device also allows simultaneous tighte-ning of the bolts. A further advantage is that assemblytimes are shortened. Reliable and Economical:The DesignAxial Exhaust MANTURBO steam turbines with anaxial exhaust flow to the condenseroffer an economical alternative to con-ventional turbines which have the
exhaust duct in lower casing half andconsequently require a mezzaninearrangement.The in-line arrangement with an axialexhaust allows significant savings in civil works. >
