In order to reduce material stresses. Under pressure, a casing has to seal against the pressure inside the casing and atmosphere. As plant pressures increase, besides geometrical designs differences, the other basic items left for the designer to minimize stresses are material selection and casing thickness. A double casing provides another option since it essentially places an intermediate casing in between the single casing. In that way, one casing seals against steam pressure and a lower partial pressure, a few stages downstream of the inlet stage, and then the intermediate casing seals against this lower pressure an ambient pressure.
